Looks like I am completely on tangent here :(

Sorry but I am not able to comprehend how the core created playback and
capture widget in the dai, which would be now used to trigger the
stream_event instead of stream name is being associated with DAPM map.

Earlier we would check the stream_name and find the widgets
corresponding to this and power up, how exactly would it work now :)
