ARM: dts: fix MMC2 regulators for Exynos5420 Arndale Octa board
Regulators for MMC2 (SD card) are PVDD_TFLASH_2V8 (LDO19) for vmmc
and PVDD_APIO_MMCOFF_2V8 (LDO13) for vqmmc. Currently the device
tree entry for MMC2 uses PVDD_PRE_1V8 (LDO10) for vmmc and vqmmc is
not specified. Fix it.
Without this patch:
- "mmc: dw_mmc: use mmc_regulator_get_supply to handle regulators"
patch causes a SD card detection to fail
- "mmc: dw_mmc: Support voltage changes" patch causes a boot hang
This patch fixes both above problems.
