drm/amd/display: Use per pipe P-State force for FPO
[Description]
* Pass in pipe index for FPO cmd to DMCUB
- This change will pass in the pipe index for each stream
that is using FPO
- This change is in preparation to enable FPO + VActive
* Use per pipe P-State force for FPO
- For FPO, instead of using max watermarks value for P-State disallow,
use per pipe p-state force instead
- This is in preparation to enable FPO + VActive
