Subject: [PATCH v4 8/8] ARM: dts: microchip: sama5d2_xplained: Add power-supply property for sdmmc0 node

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.
Add vmmc-supply and vqmmc-supply properties to sdmmc0 node.
