ASoC: fsl_sai: Add stream names for DPCM usage
DPCM needs extra dapm routes in the machine driver to route audio between Front-End and Back-End. In order to differ the stream names in the route map from CODECs, we here add specific stream names to SAI driver so that we can implement ASRC via DPCM to it.
