drm/panel: add drm_connector argument to get_modes()

Today the bridge creates the drm_connector, but that is planned
to be moved to the display drivers.
To facilitate this, update drm_panel_funcs.get_modes() to
take drm_connector as an argument.
All panel drivers implementing get_modes() are updated.

v2:
  - drop accidental change (Laurent)
  - update docs for get_modes (Laurent)
