Merge "audio: add Fast profile for USB playback - Touch tones/fast outputs and Music uses AudioStreamOut.  USB playback state is same for Media and Fast outputs  that is MUSIC. Fast output is finished playback will  clear MUSIC state in standby and it will lead to no  state for USB even though music continues leads to close  of USB playback thread. - Fix is to add different USB states for music and Fast   outputs."
