Subject: [PATCH v2 2/9] ASoC: audio-graph: Use of_node and DAI for DPCM DAI link names

For multiple instances of components, using DAI name alone for DAI links
is causing conflicts. Components can define multiple DAIs and hence using
just a device name won't help either. Thus DT device node reference and
DAI names are used to uniquely represent DAI link names.
