Series drm/ast: Detect connector status for VGA and SIL164 | expand

Commit Message

Thomas Zimmermann March 19, 2024, 8 a.m. UTC 
The .get_modes() code for VGA and SIL164 connectors does not depend
on either type of connector. Replace the driver code with the common
helper drm_connector_helper_get_modes(). It reads EDID data via
DDC and updates the connector's EDID property.
