Selecting IO voltage for the SD2
H'00: 1.8 V (VCCQ_MMC_SD2 = 1.8 V)
H'FF: 3.3 V (VCCQ_MMC_SD2 = 3.3 V)
Other than above: Setting prohibited
Note: H'00 can only be set for the SDHI SDR50/SDR104 mode and
the GPIO multiplexed with the SDHI that can be used either
3.3 V or 1.8 V.
Note that the MMC IO can only be used with 3.3 V.
