drm/panel: decouple connector from drm_panel
To facilitate moving connector creation to display drivers,
decouple the drm_connector from drm_panel.
This patch adds a connector argument to drm_panel_get_modes().
All users of drm_panel_get_modes() already had the connector
available, so updating users was trivial.
With this patch drm_panel no longer keeps a reference to the drm_connector.
