With DP MST, a digital_port can carry more than one audio stream. Hence,
more than one audio_connector needs to be attached to intel_digital_port in
such cases. However, each stream is associated with an unique encoder. So,
instead of creating an array of audio_connectors per port, move
audio_connector from struct intel_digital_port to struct intel_encoder.
This also simplifies access to the right audio_connector from codec
functions in intel_audio.c that receive intel_encoder.
