In case of hdmi connect/disconnect or when stream need to be route to
multiple monitors, corresponding port and audio infoframe needs to be
reconfigured. Currently all the configuration are done in DAI ops which
results in silence playback.

So use dapm widget event handlers to program audio infoframe and enable
/disable port configuration when widget is power on/off.
