This driver initializes a clock provider via sun8i_a23_apb0_setup
and then continues the initialization on sun8i_a23_apb0_clk_probe.
Use the new macro to notify the clk subsystem about this behaviour.

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.

The APB0 clock on A23 is a zero-based divider, not a power-of-two based
divider.
Note that this patch does not apply cleanly to kernels before 4.5-rc1,
which added CLK_OF_DECLARE support to this driver.

The APBS clock on sun9i is the same as the APB0 clock on sun8i. With
sun9i we are supporting the PRCM clocks by using CLK_OF_DECLARE,
instead of through a PRCM mfd device and subdevices for each clock
and reset control. As such we need a CLK_OF_DECLARE version of
the sun8i-a23-apb0-clk driver.
Also, build it for sun9i/A80, and not just for configurations with
MFD_SUN6I_PRCM enabled.

This platform driver has a OF device ID table but the OF module
alias information is not created so module autoloading won't work.

There is no need to init .owner field.
Based on the patch from Peter Griffin <peter.griffin@linaro.org>
"mmc: remove .owner field for drivers using module_platform_driver"
This patch removes the superflous .owner field for drivers which
use the module_platform_driver API, as this is overriden in
platform_driver_register anyway."

There are some structs and arrays on the driver that are not used
anywhere else. Let's mark them as static.

The A23 has an almost identical PRCM clock tree. The difference in
the APB0 clock is the smallest divisor is 1, instead of 2.
This patch adds a separate sun8i-a23-apb0-clk driver to support it.
