arm64: dts: renesas: rzg3s-smarc: Enable SDHI1
Add SDHI1 to RZ/G3S Smarc Carrier-II board. This is connected to a uSD
interface. Although Vccq doesn't cross the boundary of SoM it has
been added to RZ/G3S Smarc Carrier-II dtsi to have all the bits related to
SDHI1 in a single place. At the moment SoM is used only with RZ/G3S Smarc
Carrier-II board.
