[Intel-gfx] [PATCH 03/15] drm/amd/display: stop using connector->override_edid

The connector->override_edid flag is strictly for EDID override debugfs
management, and drivers have no business using it.

I really have no idea what the functional impact here is. I can only
guess that the intention is to abuse ->override_edid to block EDID
property updates. In any case, this use needs to go.

It also seems really curious we get here via connector .get_modes hook!
