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.
