drm/amd/display: Support Compliance Test Pattern Generation with DP2 Retimer
[WHY]
Certain retimer requires workarounds in order to correctly output test patterns.
[HOW]
Add vendor-specific aux sequences to program retimer's TX and pattern generator
when specific compliance test patterns are requested by sink.
Note: SQ128 w/a in DPMF mode only works in one flip orientation currently
