arm64: dts: rockchip: Disable removed devices from rk3399-nanopi-r4s

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.

[feels like the cleaner option, than to move those peripherals into a new
 rk3399-nanopi-allothers.dtsi, as the r4s variants are not as many ]
