drm/amd/display: Update FIXED_VS Retimer HWSS Test Pattern Sequences
[WHY]
Need to fix some broken logic and sequencing in initial commit
[HOW]
Fix logic handling override deprogramming when exiting SQ128.
Don't exit early from dp_set_hw_lane_settings for DP2/FIXED_VS case.
Move LTTPR 128b/132b check out of requires_hwss and check during
runtime, as LTTPR caps are not populated on initial call.
Add pending_test_pattern to link state to allow HWSS to set FFE overrides
on retimer TX and/or skip setting APU TX FFE depending on requested pattern.
Use updated clock source for SQ128 override sequence.
Skip HW FFE preset programming when performing test pattern overrides.
