drm/bridge: connector: add support for HDMI codec framework

Add necessary glue code to be able to use new HDMI codec framework from
the DRM bridge drivers. The drm_bridge implements a limited set of the
hdmi_codec_ops interface, with the functions accepting both
drm_connector and drm_bridge instead of just a generic void pointer.

This framework is integrated with the DRM HDMI Connector framework, but
can also be used for DisplayPort connectors.
