Rename r8a73a4_init_delay() into r8a73a4_init_early()
to make the function name show that more than just
delay setup may happen in the future.

This patch adds a sample DT-based APE6EVM "reference" implementation. The
use of platform-specific C-code should be avoided with this configuration
as much as possible.

Function GPIOs are not used anymore, and all code use the GPIO numbers
directly. Remove the GPIOs enumeration.

The r8a73a4 SoC has sparse GPIO numbers. Declare ranges for pin numbers
in the PFC SoC data. Pin numbers shall be used with the GPIO API from
this point on.

Add initial PFC support for the r8a73a4 SoC.

At this point only GPIO interface is supported, move to newer interfaces
planned as incremental changes.

Original authors are Morimoto-san with help from Yoshii-san, thanks to
them for the heavy lifting. Adjusted by Magnus to work together with
updated code in drivers/pinctrl.

V3 of initial support for the r8a73a4 SoC including:
 - Single Cortex-A15 CPU Core
 - GIC
 - Architecture timer

No static virtual mappings are used, all the components
make use of ioremap(). DT_MACHINE_START is still wrapped
in CONFIG_USE_OF to match other mach-shmobile code.
