[PATCH v2 2/8] ARM: dts: microchip: sam9x60ek: Add power-supply properties for sdmmc nodes

[Mihai Sain]

The sdmmc0 and sdmmc1 controllers are powered from 3.3V regulator.
Add vmmc-supply and vqmmc-supply properties to sdmmc nodes.
The sdmmc controller from SAM9X60 MPU doesn't support the IO voltage signaling/switching required by the UHS sd-card.
In order to use the sd high-speed mode, keep vqmmc at 3V3.
