There are a few very theoretical off-by-one bugs in report descriptor size
checking when performing a pre-parsing fixup. Fix those.

The change to support Genius Manticore Keyboard also changed behaviour
for Genius Gx Imperator Keyboard, as there is no break between the
cases. This is presumably a mistake.
Reported by Coverity as CID 1134029.

The manticore keyboard requires that all usb EP are opened at least
once to be fully functional. The third EP forwards to the user space
some vendor specific information about the keyboard state, but are useless
currently for the kernel.
Opening them and closing them makes the keyboard responsive again.

Genius Manticore Keyboard presents the same problem in its report
descriptors than Genius Gila Gaming Mouse and Genius Imperator Keyboard.
Use the same fixup.

Genius Gx Imperator Keyboard presents the same problem in its report

Use the same fixup for both.

Genius Gila Gaming Mouse presents an obviously wrong report descriptor.
the Consumer control (report ID 3) is the following:
0x05, 0x0c, // Usage Page (Consumer Devices) 105
0x09, 0x01, // Usage (Consumer Control) 107
0xa1, 0x01, // Collection (Application) 109
0x85, 0x03, // Report ID (3) 111
0x19, 0x00, // Usage Minimum (0) 113
0x2a, 0xff, 0x7f, // Usage Maximum (32767) 115
0x15, 0x00, // Logical Minimum (0) 118
0x26, 0xff, 0x7f, // Logical Maximum (32767) 120
0x75, 0x10, // Report Size (16) 123
0x95, 0x03, // Report Count (3) 125
0x81, 0x00, // Input (Data,Arr,Abs) 127
0x75, 0x08, // Report Size (8) 129
0x95, 0x01, // Report Count (1) 131
0x81, 0x01, // Input (Cnst,Arr,Abs) 133
0xc0, // End Collection 135
So the first input whithin this report has a count of 3 but a usage range
of 32768. So this value is obviously wrong as it should not be greater than
the report count.

This allows the hid drivers to be independent from the transport layer.
The patch was constructed by replacing all occurences of
usbhid_submit_report() by its hid_hw_request() counterpart.
Then, drivers not requiring USB_HID anymore have their USB_HID
dependency cleaned in the Kconfig file.
Finally, few drivers still depends on USB_HID. Many of them
are requiring the io wait callback. They are found in the next patch.

Use the new module_hid_driver macro in all HID drivers that have
a simple register/unregister init/exit.
This also converts the hid drivers that test for a failure of
hid_register_driver() and report the failure. Using module_hid_driver
in those drivers removes the failure message.

Neaten current uses of dev_<level> by adding and using
hid specific hid_<level> macros.
Convert existing uses of dev_<level> uses to hid_<level>.
Convert hid-pidff printk uses to hid_<level>.
Remove err_hid and use hid_err instead.
Add missing newlines to logging messages where necessary.
Coalesce format strings.
Add and use pr_fmt(fmt) KBUILD_MODNAME ": " fmt
Other miscellaneous changes:
Add const struct hid_device * argument to hid-core functions
extract() and implement() so hid_<level> can be used by them.
Fix bad indentation in hid-core hid_input_field function
that calls extract() function above.

Update hid_driver's report_fixup prototype to allow changing report
descriptor size and/or returning completely different report descriptor.
Update existing usage accordingly.
This is to give more freedom in descriptor fixup and to allow having a whole
fixed descriptor in the code for the sake of readability.

This removal was scheduled and there is no problem with later
distros to adapt for the new bus, thanks to aliases.
module-init-tools map files are deprecated nowadays, so that
the patch which introduced hid ones into the m-i-t won't be
accepted and hence there is no reason for leaving compat stuff in.

This device sends several buttons in a separate field, which is
wrongly described in the report descriptor. Fix it in the following
way:
- change led usage page to button
- report size 8 count 1 becomes report size 1 count 8
- the button usage range changed to 4-7 (the mouse has three buttons in
a different field already).
