sh: Break out SuperH PFC code
This file breaks out the SuperH PFC code from arch/sh/kernel/gpio.c + arch/sh/include/asm/gpio.h to drivers/sh/pfc.c + include/linux/sh_pfc.h. Similar to the INTC stuff. The non-SuperH specific file location makes it possible to share the code between multiple architectures.
