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. Signed-off-by: Chen-Yu Tsai <wens@kernel.org> [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 ] Link: https://patch.msgid.link/20260505172903.33271-1-wens@kernel.org Signed-off-by: Heiko Stuebner <heiko@sntech.de>
