ASoC: Intel: avs: Initialize private data for subsequent HDA FEs
HDAudio implementation found in sound/pci/hda expects a valid stream pointer in substream->runtime->private_data location. For ASoC users, that should point to a valid link stream which is assigned when BE opens. As BE borrows its runtime from FE, the information may be lost when reparenting comes into picture - see dpcm_be_reparent(). To support the DPCM reparenting functionality for HDAudio scenarios while still fulfilling expectations of HDAudio common code, have all FEs point to the same private data.
