Add vmmc-supply and vqmmc-supply properties to sdmmc nodes. The sdmmc controller from SAMA5D2 MPU has support for IO voltage signaling/switching required by the UHS sd-card. In order to avoid the issues from the tuning procedure required by the UHS cards, keep the vqmmc at 3V3 to use the sd high-speed mode.
