ARM: mach-shmobile: r8a7779 PFC GPIO-only prototype

From: Magnus Damm <[email protected]>

Initial r8a7779 PFC prototype support.

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.

This prototype requires a filthy mapping hack for the PFC/GPIO base addresses applied on top of this patch to workt. The pfc code needs to be extended to make use of ioremap() to support this SoC.
