[PATCH 5.4 048/434] drm: exynos: exynos_hdmi: use cec_notifier_conn_(un)register

From: Dariusz Marcinkiewicz <darekm@google.com>

[ Upstream commit 71137bfd98973efb7b762ba168df077b87b34311 ]

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 v7:
- err_runtime_disable -> err_rpm_disable
Changes since v2:
- removed unnecessary call to invalidate phys address before
deregistering the notifier,
- use cec_notifier_phys_addr_invalidate instead of setting
invalid address on a notifier.
