arm64: dts: rockchip: Enable the missing av1d nodes

[nyanmisaka]

Required by the RKMPP AV1 hardware decoding in
Chromium (libv4l-rkmpp), FFmpeg and Gstreamer.

The av1d and av1_mmu nodes are disabled by default as per

linux-rockchip/arch/arm64/boot/dts/rockchip/rk3588s.dtsi

Lines 4353 to 4385 in a93767d

Tested with a few clips and it also works on Rock-5C.

Old 5.10 kernel doesn't need av1d enabled. AV1 decoding would work with av1d_mmu. And most of these devicetrees are copied from 5.10 branch, that's why.
