ARM: dts: exynos: Add eMMC and SD regulator supplies to Odroid XU3/XU4

Add vmmc and vqmmc supplies from MF circuit sheets for eMMC and SD on
odroid XU3 and XU4 to avoid warnings:

dwmmc_exynos 12200000.mmc: Looking up vmmc-supply property in node /mmc@12200000 failed

Also remove their always_on properties so the regulators could be
disabled when not used.
