ASoC: hdac_hdmi: Begin to add support for DP Multi-stream audio
With MST each pin contains several ports to which device can be connected. As a preparatory work to support DP MST this patch adds below changes: 1. Defines the port structure and moves all stream related information like ELD, converter list, chmap to port. 2. Creates ports for each pin based on the max_ports support. 3. Based on Pin-Port combination creates DAPM Mux widget instead of Pin to allow user to select a converter. 4. Port zero is the default port when pin does not support MST.
