arm64: dts: renesas: rzg2ul-smarc-som: Enable eMMC on SMARC platform
RZ/G2UL SoM has both 64GB eMMC and microSD connected to SDHI0.
Both these interfaces are mutually exclusive and the SD0 device
selection is based on SW1[2] on SoM module.
Set SW1[2] to position OFF for selecting eMMC
Set SW1[2] to position ON for selecting microSD
This patch enables eMMC on RZ/G2UL SMARC platform by default.
