Subject: [PATCH 2/3] ARM: dts: use vmmc-supply of emmc/sd for exynos5422-odroidxu3

Added support for vmmc/vqmmc-supply for emmc/sd cards.
Fixed the min values for regulator ldo13_reg (VDDQ_MMC2).
Added ramp-delay for LDO9(VDD33_USB3_0).
Added ramp-delay for LDO13(VDDQ_MMC2).
Added ramp-delay for LDO15(ETH_P3V3).

Signed-off-by: Anand Moon <linux.amoon@...il.com>
