ASoC: hdac_hdmi: Register widget event handlers
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.
