arm64: dts: renesas: rzg2ul-smarc: Enable microSD on SMARC platform

Enable the microSD card slot connected to SDHI1 on the RZ/G2UL SMARC
platform by removing the sdhi1 override which disabled it, and by adding
the necessary pinmux required for SDHI1.

This patch also adds gpios property to vccq_sdhi1 regulator.
