arm64: dts: renesas: rzg3s-smarc-som: Enable eMMC by default

Enable eMMC by default on the RZ/G3S SMARC platform, as previously done
on RZ/G2L boards and other Renesas platforms.

The SW_CONFIG2 setting selects between the uSD0 card and eMMC. By setting
SW_CONFIG2 to SW_OFF, we select eMMC by default.
