hal : Overwrite the APP type for PCM RX and TX path

 -For all the rx/tx sessions hal sends the default app type 'general playback'
  with acdb cal data if output policy conf file is not added.So it sets the SA+
  topo id for POPP.
 -With output policy conf file it would create the
  multiple instance of COPP for different output with different app type,
  which is not recommended for resource constrained target.So we can not
  add the output policy conf file with different app types to avoid SA+.
 -Overwrite the app type for PCM Rx and Tx path to avoid setting SA+ for POPP.
