Subject: [PATCH] arm64: dts: rockchip: enable UFS controller on
 FriendlyElec NanoPi M5

The NanoPi M5 board supports pluggable UFS modules using the UFSHC
inside its Rockchip RK3576 SoC.

Enable the respective devicetree node.

Board specific supply regulators are not added, because they are all
non-gateable descendants of other regulators marked always-on.
