hal: Fix incorrect MBDRC volume level for music use case. 

 -In concurrent use case of music playback and touch tone,
  MBDRC volume level appiled for music is not correct because
  Music stream was not added to use case list. But volume
  level was not cached as calibration for low latency was set
  successfully.
 -cache MBDRC volume level always and apply it once stream
  is started.
