ARM: dts: at91: sama7g5ek: align power rails for sdmmc0/1

Browse Source 
On this board SDMMC0 has a 1.8 signaled eMMC device powered at
3.3V. Hence, correctly describe the connected rails from the PMIC.

SDMMC1 is connected to a voltage switch that can change from
3.3V to 1.8V by a hardware controlled pin.
However SDMMC1 at the moment works only in 3.3V mode (default speed,
no UHS-I modes), thus connect the signaling to the 3.3V rail.
