docs: process: remove outdated submitting-drivers.rst

Commit 31b24bee3357 ("docs: add a warning to submitting-drivers.rst")
in October 2016 already warns "This (...) should maybe just be deleted,
but I'm not quite ready to do that yet".

Maybe, six years ago, we were not ready but let us remove old content
for the better now and structure and maintain less content in the kernel
documentation with a better result.

Drop this already outdated document and adjust all textual references.

Here is an argument why deleting the content will not remove any useful
information to the existing kernel documentation, individually broken down
for each section.

Section "Allocating Device Numbers" refers to https://www.lanana.org/, and
then refers to Documentation/admin-guide/devices.rst.

However, the devices.rst clearly states:

  "The version of this document at lanana.org is no longer maintained."

Everything needed for submitting drivers is already stated in devices.rst
and the reference to https://www.lanana.org/ is outdated, and should be
just deleted.

Section "Who To Submit Drivers To" is all about Linux 2.0 - 2.6, before
the new release version scheme; the mentioned developers are still around,
but actually not the first developers to contact anymore.

Section "What Criteria Determine Acceptance" has a few bullet points:

Licensing and Copyright is well-covered in process/kernel-license.rst.

Interfaces, Code, Portability, Clarity state some obvious things about
ensuring kernel code quality.

Control suggests to add a MAINTAINERS entry, which is already mentioned in
6.Followthrough.rst: "... added yourself to the MAINTAINERS file..."

PM support states a bit about implementing and testing power management of
a driver, it remains an open question where to place that in the process
documents. Driver developers interested in power management will find the
corresponding part on power management in the kernel documentation anyway.

In section "What Criteria Do Not Determine Acceptance", the points Vendor
and Author states something basic consequence of the kernel being an
open-source community software development. Probably no need to mention it
nowadays.

Section "Resources" lists resources that are also mentioned elsewhere more
central.

-Submitting Drivers For The Linux Kernel
-=======================================
-
-This document is intended to explain how to submit device drivers to the
-various kernel trees. Note that if you are interested in video card drivers
-you should probably talk to XFree86 (https://www.xfree86.org/) and/or X.Org
-(https://x.org/) instead.
-
-.. note::
-
-   This document is old and has seen little maintenance in recent years; it
-   should probably be updated or, perhaps better, just deleted.  Most of
-   what is here can be found in the other development documents anyway.
-
-   Oh, and we don't really recommend submitting changes to XFree86 :)
-
-Also read the :ref:`Documentation/process/submitting-patches.rst <submittingpatches>`
-document.
-
-
-Allocating Device Numbers
--------------------------
-
-Major and minor numbers for block and character devices are allocated
-by the Linux assigned name and number authority (currently this is
-Torben Mathiasen). The site is https://www.lanana.org/. This
-also deals with allocating numbers for devices that are not going to
-be submitted to the mainstream kernel.
-See :ref:`Documentation/admin-guide/devices.rst <admin_devices>`
-for more information on this.
-
-If you don't use assigned numbers then when your device is submitted it will
-be given an assigned number even if that is different from values you may
-have shipped to customers before.
-
-Who To Submit Drivers To
-------------------------
-
-Linux 2.0:
-	No new drivers are accepted for this kernel tree.
-
-Linux 2.2:
-	No new drivers are accepted for this kernel tree.
-
-Linux 2.4:
-	If the code area has a general maintainer then please submit it to
-	the maintainer listed in MAINTAINERS in the kernel file. If the
-	maintainer does not respond or you cannot find the appropriate
-	maintainer then please contact Willy Tarreau <w@1wt.eu>.
-
-Linux 2.6 and upper:
-	The same rules apply as 2.4 except that you should follow linux-kernel
-	to track changes in API's. The final contact point for Linux 2.6+
-	submissions is Andrew Morton.
-
-What Criteria Determine Acceptance
-----------------------------------
-
-Licensing:
-		The code must be released to us under the
-		GNU General Public License. If you wish the driver to be
-		useful to other communities such as BSD you may release
-		under multiple licenses. If you choose to release under
-		licenses other than the GPL, you should include your
-		rationale for your license choices in your cover letter.
-		See accepted licenses at include/linux/module.h
-
-Copyright:
-		The copyright owner must agree to use of GPL.
-		It's best if the submitter and copyright owner
-		are the same person/entity. If not, the name of
-		the person/entity authorizing use of GPL should be
-		listed in case it's necessary to verify the will of
-		the copyright owner.
-
-Interfaces:
-		If your driver uses existing interfaces and behaves like
-		other drivers in the same class it will be much more likely
-		to be accepted than if it invents gratuitous new ones.
-		If you need to implement a common API over Linux and NT
-		drivers do it in userspace.
-
-Code:
-		Please use the Linux style of code formatting as documented
-		in :ref:`Documentation/process/coding-style.rst <codingStyle>`.
-		If you have sections of code
-		that need to be in other formats, for example because they
-		are shared with a windows driver kit and you want to
-		maintain them just once separate them out nicely and note
-		this fact.
-
-Portability:
-		Pointers are not always 32bits, not all computers are little
-		endian, people do not all have floating point and you
-		shouldn't use inline x86 assembler in your driver without
-		careful thought. Pure x86 drivers generally are not popular.
-		If you only have x86 hardware it is hard to test portability
-		but it is easy to make sure the code can easily be made
-		portable.
-
-Clarity:
-		It helps if anyone can see how to fix the driver. It helps
-		you because you get patches not bug reports. If you submit a
-		driver that intentionally obfuscates how the hardware works
-		it will go in the bitbucket.
-
-PM support:
-		Since Linux is used on many portable and desktop systems, your
-		driver is likely to be used on such a system and therefore it
-		should support basic power management by implementing, if
-		necessary, the .suspend and .resume methods used during the
-		system-wide suspend and resume transitions.  You should verify
-		that your driver correctly handles the suspend and resume, but
-		if you are unable to ensure that, please at least define the
-		.suspend method returning the -ENOSYS ("Function not
-		implemented") error.  You should also try to make sure that your
-		driver uses as little power as possible when it's not doing
-		anything.  For the driver testing instructions see
-		Documentation/power/drivers-testing.rst and for a relatively
-		complete overview of the power management issues related to
-		drivers see :ref:`Documentation/driver-api/pm/devices.rst <driverapi_pm_devices>`.
-
-Control:
-		In general if there is active maintenance of a driver by
-		the author then patches will be redirected to them unless
-		they are totally obvious and without need of checking.
-		If you want to be the contact and update point for the
-		driver it is a good idea to state this in the comments,
-		and include an entry in MAINTAINERS for your driver.
-
-What Criteria Do Not Determine Acceptance
------------------------------------------
-
-Vendor:
-		Being the hardware vendor and maintaining the driver is
-		often a good thing. If there is a stable working driver from
-		other people already in the tree don't expect 'we are the
-		vendor' to get your driver chosen. Ideally work with the
-		existing driver author to build a single perfect driver.
-
-Author:
-		It doesn't matter if a large Linux company wrote the driver,
-		or you did. Nobody has any special access to the kernel
-		tree. Anyone who tells you otherwise isn't telling the
-		whole story.
