[why]
The Apple Studio Display primary tile advertises both the full 5120x2880
mode and the per-tile 2560x2880 timing. With the secondary tile already
hidden from userspace, the stray 2560x2880 mode on the primary connector
can still be picked by compositors, defeating the single 5K stream goal.
[how]
Prune the per-tile timing from the primary connector during get_modes:
when the sink carries the disable_second_tile quirk and the connector is
the primary tile (tile_h_loc == 0 && tile_v_loc == 0), drop any probed
mode matching the advertised tile size (tile_h_size x tile_v_size) so
userspace only sees the full 5120x2880 mode.
