Enable of rkvdec0 should probably be split out from the patch that adds
the rkvdec0 node to soc dtsi.
Also why is rkvdec0 only enabled on rock-5b and orangepi-5?

Blank line is missing.

iommus and resets should probably be added.

The iommu node for rkvdec0_mmu seem to be missing, is it not required to
be able to use memory >4GiB as decoding buffers?
I would also consider adding the rkvdec1 node(s), if I am understanding
correctly they can both be used in a cluster or completely independent.
Also on RK3582/RK3583 one (or both) of the decoder cores may be marked
as bad, yet the remaining one can still be used independently. The idea
will be that bootloader fixup the DT and disabled/delete-node the bad
core(s).
