Subject[PATCH v7 6/9] drm: sti: use cec_notifier_conn_(un)register
From
Use the new cec_notifier_conn_(un)register() functions to
(un)register the notifier for the HDMI connector, and fill
in the cec_connector_info.

Changes since v2:
Don't invalidate physical address before unregistering the
notifier.
