[PATCH] arm64: dts: rockchip: rk3399-nanopi-r4s: Disable removed devices

[Chen-Yu Tsai]

While the design of the NanoPi R4S is based on the common NanoPi 4
family, it is trimmed down a lot.

Disable all the peripherals on the SoC that are not used, and delete
all the external components that are not present.
