drm/amd/display: Clear edid when unplug mst connector
[Why]
When unplug one sst monitor from a mst hub and plug in the same
port with another sst monitor, we don't read the corresponding
edid. That's because we detect there is already an edid stored in
aconnector->edid which is a stale one.
[How]
Clean up aconnector->edid when unplug mst connector.
