ARM: shmobile: ape6evm: update MMC0, SDHI0 and SDHI1 with correct regulators
Currently a dummy fixed always-on regulator is used for all 3 SD/MMC
interfaces on ape6evm. This patch updates the board to use correct supplies
for MMC0, SDHI0 and SDHI1 VDD. SDHI0 VccQ supply regulator should be
implemented in a separate patch.
