ARM: shmobile: armadillo800eva: add a fixed voltage regulator for SDHI1

Browse source

The SDHI1 power supply on armadillo800eva can be switched on and off. In
the current version this is not used and the regulator is hard-wired to
"on." This patch switches SDHI1 to a proper fixed-voltage regulator,
using a GPIO to enable and disable it. Both SDHI0 and SDHI1 ports shall
now be specifying the MMC_CAP_POWER_OFF_CARD MMC capability. Both
interfaces tested with an SDIO card.
