[PATCH v7 6/9] drm: sti: use cec_notifier_conn_(un)register

[Dariusz Marcinkiewicz <darekm@google.com>]

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.
