drm/amd/display: Skip PHY SSC reduction on some 8K panels
[Why]
Some 8K displays cannot tolerate the reduced phy ssc value
at high link utilization and show corruption or black screen.
[How]
Add an EDID panel-id quirk to utilize existing skip_phy_ssc_reduction flag.
To pass the link into the quirk handler, change the signature of
apply_edid_quirks() to take link as an argument. The dev local in
dm_helpers_parse_edid_caps() becomes unused and is removed.
