drm/amd/display: Unlock Pipes Based On DET Allocation
[Why]
DML21 does not allocate DET evenly between pipes.
May result in underflow when unlocking the pipes as DET could
be overallocated.
[How]
1. Unlock pipes that have a decreased amount of DET allocation
2. Wait for the double buffer to be updated.
3. Unlock the remaining pipes.
