ASoC: hdac_hdmi: Add machine pin widget for each port

Represent each port as machine DAPM pin widget. This helps in
enable/disable pin when monitor is connected/disconnected in case pcm
is rendered to multiple ports.

Create machine pin widgets  and pin switch kcontrol for each port and
report based on the pin status
