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.
