drm: exynos: exynos_hdmi: use cec_notifier_conn_(un)register

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.
