arm64: dts: renesas: rzg3s-smarc-som: Enable SDHI2
Add SDHI2 to RZ/G3S Smarc SoM. SDHI2 pins are multiplexed with SCIF1,
SSI0, IRQ0, IRQ1. The selection b/w SDHI2 and SCIF1, SSI0, IRQ0, IRQ1
is done with a switch button. To be able to select b/w these a
compilation flag has been added (SW_SD2_EN) at the moment being
instantiated to select SDHI2.
