drm/amd/display: DML Validation Dump/Check with Logging
[Why]
Need validation that we are programming the expected values (rq, ttu, dlg)
from DML. This debug feature will output logs if we are programming
incorrect values and may help differentiate DAL issues from HW issues.
[How]
Dump relevant registers for each pipe with active stream. Compare current
reg values with the converted DML output. Log mismatches when found.
