The RDP433 has NAND and eMMC variants. Presently, only NAND variant is
supported. To enable support for eMMC variant, add the relevant GPIO
related information.

Do not enable NAND by default here. Enable it in board specific DTS.

v4: Move sdhc properties from emmc dts to SoC dtsi

v3: Disable nand in ipq9574-rdp-common.dtsi and enable it where required.
