74eb436ec0 ARM: mach-shmobile: r8a7779 PFC IPSR4 fix
Fix the bit field width information for the IPSR4 register
in the r8a7779 pin function controller (PFC).

Without this fix the Marzen board fails to receive data
over the serial console due to misconfigured pin function
for the RX pin.

19c43fc538 ARM: mach-shmobile: r8a7779 PFC GPIO-only support V2
Add GPIO-only r8a7779 PFC support V2.

Only regular GPIOs are supported at this time. GPIO_FN are not
supported because they require variable bit width support in be
the shared pfc code.
