drm/amd/display: hide Apple Studio Display secondary tile

The Apple Studio Display exposes a 2x1 tiled panel over two SST DP
links. The primary tile advertises the full 5120x2880 mode (with DSC on
the bandwidth-sufficient link) while the secondary carries a per-tile
2560x2880 timing on a link without sufficient bandwidth. Report the
non-primary tile connector as disconnected during detect so compositors
only see the primary DP link and configure a single 5K mode instead of
driving both tiled streams independently.

Drive the behaviour from an EDID quirk: add a disable_second_tile panel
patch that apply_edid_quirks() sets for the affected Apple Studio
Display panel IDs (0xAE3A, 0xAE42, 0xAE46), and have detect() hide the
secondary tile when the sink carries that quirk.
