This series contains 3 patches:
1. Add a few new generic edp panels.
2. Support a new quirk to override the mode read from edid
3. Only add hard-coded mode if both edid and hard-coded modes presents.

2.42.0.869.gea05f2083d-goog
According to decoding edid and datahseet:
- Rename AUO 0x235c B116XTN02 to B116XTN02.3
- Rename AUO 0x405c B116XAK01 to B116XAK01.0 and adjust the timing of
auo_b116xak01: T3=200, T12=500, T7_max = 50.
Fixes: 3db2420422a5 ("drm/panel-edp: Add AUO B116XTN02, BOE NT116WHM-N21,836X2, NV116WHM-N49 V8.0")
Fixes: da458286a5e2 ("drm/panel: Add support for AUO B116XAK01 panel")

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.
