In an effort parallel to [1], the GPU clock controller requires more than 0/1 power domains to function properly. Describe these dependencies to ensure the hardware can always power on safely. Patches 1 & 2 are separate (but related) fixes, which need to be merged before the DT change for SC8280XP. Posting as RFC since I only got to test it on SC8280XP(-crd).
