arm64: dts: renesas: rzt2h-n2h-evk-common: Use GPIO for SD0 write protect

Switch SD0 write-protect detection to a GPIO on the RZ/T2H and RZ/N2H
EVKs. Both boards use a full-size SD card slot on the SD0 channel with
a dedicated WP pin.

The RZ/T2H and RZ/N2H SoCs use of_data_rcar_gen3, which sets
MMC_CAP2_NO_WRITE_PROTECT and causes the core to ignore the WP signal
unless a wp-gpios property is provided. Describe the WP pin as a GPIO
to allow the MMC core to evaluate the write-protect status correctly.
