Dariusz Marcinkiewicz 7070fe7386 drm: dw-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 v6:
        - move cec_notifier_conn_unregister to a bridge detach
	  function,
	- add a mutex protecting a CEC notifier.
Changes since v4:
	- typo fix
Changes since v2:
	- removed unnecessary NULL check before a call to
	cec_notifier_conn_unregister,
	- use cec_notifier_phys_addr_invalidate to invalidate physical
	address.
Changes since v1:
	Add memory barrier to make sure that the notifier
	becomes visible to the irq thread once it is fully
	constructed.
