If a non generic edp-panel is under aux-bus, the mode read from edid would
still be selected as preferred and results in multiple preferred modes,
which is ambiguous.
If both hard-coded mode and edid exists, only add mode from hard-coded.

Generic edp gets mode from edid. However, some panels report incorrect
mode in this way, resulting in glitches on panel. Introduce a new quirk
additional_mode to the generic edid to pick a correct hardcoded mode.

Add a function to clear the preferred bit of a connector's existing modes.
This is useful for edp panel to unset the preferred modes read from edid
if the panel has hard-coded modes.
