Implement generic framework to be used by these drivers. This removes a requirement to implement get_eld() callback and provides default implementation for codec's plug handling. The framework is integrated with the DRM HDMI Connector framework, but can be used by DisplayPort 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.

Such tasks include setting or invalidating CEC address, notifying HDMI codec driver, updating scrambler data, etc. Implementing such tasks in a driver-specific callbacks is error prone.
