Yes. As I wrote it might be not the optimal solution.

All targets earlier than sm8150. SDE driver sets SDE_DSC_OUTPUT_CTRL
if for v1 CTL blocks (sm8150+).

But we should still bind the DSC to the PP block, shouldn't we? So
from the software point of view it is the same situation: PP_DITHER
supports any DSC (1.2) and should be bound to it.

I think it would be better to still return PP from the RM. It's that
the RM will have to return PP/DSC in pairs.
