ASoC: hdac_hdmi: Add support to handle MST capable pin
To handle jack event and configuration of the pin widget for MST
capable pin, this patch adds:
o Flag to identify the pin is MST capable.
o In notify callback(), based on the pipe and port information marks if
the port is mst_capable. In case of non MST, port is defaulted to zero.
