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.

a=openpgp; fpr=8F88381DD5C873E4AE487DA5199BF1243632046A 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.

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. Start implementing the generic helper function (currently handling only the HDMI Codec framework) to be used by drivers utilizing HDMI Connector framework.
