drm/display: hdmi-cec-helper: Fix adapter unregistration

Attempting to reload a kernel module of an HDMI driver making use of the
new CEC helpers revealed a resource deallocation issue, i.e. the entries
in /dev/cec* keep growing.

Moreover, after a couple of tries the kernel crashes and the whole
system freezes:

Do a proper cleanup by calling cec_unregister_adapter() instead of
cec_delete_adapter() in the managed release action handler.

drm/display: add CEC helpers code

Add generic CEC helpers to be used by HDMI drivers. Both notifier and
and adapter are supported for registration. Once registered, the driver
can call common set of functions to update physical address, to
invalidate it or to unregister CEC data. Unlike drm_connector_cec_funcs
(which provides interface common to all implementations, including, but
not limited to the CEC adapter, CEC notifier, CEC pin-based adapter,
etc) the struct drm_connector_hdmi_cec_adapter_ops provides callbacks
specific to the CEC adapter implementations.
