The Kconfig currently controlling compilation of this code is:
drivers/mfd/Kconfig:config MFD_SUN6I_PRCM
drivers/mfd/Kconfig: bool "Allwinner A31 PRCM controller"
...meaning that it currently is not being built as a module by anyone.
Lets remove the couple traces of modularity so that when reading the
driver there is no doubt it is builtin-only.
Since module_platform_driver() uses the same init level priority as
builtin_platform_driver() the init ordering remains unchanged with
this commit.
We also delete the MODULE_LICENSE tag etc. since all that information
is already contained at the top of the file in the comments.

The Allwinner A23 SoC has a PRCM unit like the previous A31 SoC.
The differences are the AR100 clock can no longer be modified,
the APB0 clock has different divisors, and some clock gates are
gone.
This patch adds a compatible with a modified subdevice list for
the A23.

The PRCM (Power/Reset/Clock Management) block exposes several subdevices
in different subsystems (clk, reset ...)
Add basic support for the PRCM unit with clk (AR100, AHB0, and APB0 clks)
and reset controller subdevices.
Other subdevices might be added later (if needed).
