ARM: mach-shmobile: Kota2 SDHI0 and SDHI1 support
Add SDHI0 and SDHI1 support to the Kota2 board. SDHI0 is hooked up to a microSD card slot and SDHI1 to a wireless module that also connects to SCIFB. This depends on the recently merged code for TMIO_MMC_HAS_IDLE_WAIT together with PFC support for pull-ups on SDHI0 and SDHI1.
