drm/amd/display: Do 1-to-1 mapping between OPP and DSC in DML2
[why]
To determine which block instance to power-gate,
we look at the available pipe resource for both plane
and stream. On MPO, DSC3 was falsely powered on even
though only 1 stream path was enabled because
the resource mapping was not done correctly.
[how]
Acquire the correct DSC instance to power on / off based
on the instance of OPP which determines the backend
pipe index.
