Linux commit afeccc408496 ("arm64: dts: rockchip: add DT entry for RNG
to RK356x") merged for v6.12-rc1 add a proper rng node to the SoC DT.

Remove the rng node from SoC u-boot.dtsi now that the rng driver support
the compatible used in dts/upstream DT. Ensure the rng node is enabled
to support rng on RK3566 variants.
