[PATCH v6 2/6] arm64: dts: rockchip: enable UFS controller on FriendlyElec NanoPi M5

[Alexey Charkov]

From: Alexey Charkov <alchark at gmail.com>

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

Enable the respective devicetree node and add its supply regulators.
