Subject: [PATCH v4 22/27] drm/panel: panel-simple: Remove extra call: drm_connector_update_edid_property()

As of commit 5186421cbfe2 ("drm: Introduce epoch counter to
drm_connector") the drm_get_edid() function calls
drm_connector_update_edid_property() for us. There's no reason for us
to call it again.

As Laurent pointed out [1] this is actually a pretty common
problem. His suggestion to do this more broadly is a good idea but
this series is probably a bit ambitious already so I would suggest
that be taken up separately.
