It will cause null-ptr-deref if platform_get_resource() returns NULL,
we need check the return value.

Now that we've gotten rid of clk_readl() we can remove io.h from the
clk-provider header and push out the io.h include to any code that isn't
already including the io.h header but using things like readl/writel,
etc.
Found with this grep:

I also reordered a couple includes when they weren't alphabetical and
removed clk.h from kona, replacing it with clk-provider.h because
that driver doesn't use clk consumer APIs.

Our MMC host driver now issues a reset, instead of just deasserting
the reset control, since commit c34eda69ad4c ("mmc: sunxi: Reset the
device at probe time"). The sun9i-mmc clock driver does not support
this, and will fail, which results in MMC not probing.
This patch implements the reset callback by asserting the reset control,
then deasserting it after a small delay.

Commit a53e35db70d1 ("reset: Ensure drivers are explicit when requesting
reset lines") started to transition the reset control request API calls
to explicitly state whether the driver needs exclusive or shared reset
control behavior. Convert all drivers requesting exclusive resets to the
explicit API call so the temporary transition helpers can be removed.
No functional changes.

We have the following file --> Kconfig mapping:
sunxi/clk-factors.c obj-y
sunxi/clk-sun6i-apb0-gates.c CONFIG_MFD_SUN6I_PRCM (bool)
sunxi/clk-sun6i-apb0.c CONFIG_MFD_SUN6I_PRCM
sunxi/clk-sun6i-ar100.c CONFIG_MFD_SUN6I_PRCM
sunxi/clk-sun8i-apb0.c CONFIG_MFD_SUN6I_PRCM
sunxi/clk-sun9i-mmc.c obj-y
Hence none of these are being built as a module by anyone.
Lets remove the modular code that is essentially orphaned, so that
when reading the drivers there is no doubt they are builtin-only. All
drivers get mostly the same changes, so they are handled in batch.
Changes are (1) convert to builtin_platform_register, (2) use the
init.h header, (3) delete the MODULE_LICENCE/MODULE_AUTHOR and
associated tags, and (4) delete any ".remove" functions.
There was a stray module.h in a file not using any init.h or
module.h stuff, so we simply removed that one.
In two cases, we explicitly disallow a driver unbind, since that
doesn't have a sensible use case anyway, and it allows us to drop
the ".remove" code for non-modular drivers.
Since module_platform_driver() uses the same init level priority as
builtin_platform_driver() the init ordering remains unchanged with
this commit.
We delete the MODULE_LICENSE etc. tags since all that information
is already contained at the top of each file in the comments.

This clock provider uses the consumer API, so include clk.h
explicitly. Also remove clkdev.h in files that aren't using it
and include slab.h when clkdev.h was being used to implicitly
include it.

On the A80 SoC, the 4 mmc controllers each have a separate register
controlling their register access clocks and reset controls. These
registers in turn share a ahb clock gate and reset control.
This patch adds a platform device driver for these controls. It
requires both clocks and reset controls to be available, so using
CLK_OF_DECLARE might not be the best way.
