drm/panel-edp: Add override_edid_mode quirk for generic edp

Browse source

[ Upstream commit 9f7843b515 ]

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.
