Add a num_analog_stream_encoders field to indicate how many analog stream encoders are present. When analog stream encoders are present, create them. Additionally, add an analog_engine field to link encoders and search for supported analog encoders in the BIOS for each link. When connecting an RGB signal, search for analog stream encoders. The actual DCE analog link and stream encoder is going to be added in a subsequent commit. v2: Add check to see if an analog engine is really supported.
