ASoC: Intel: avs: HDA PCM BE operations

Browse source

HDA streaming in DSP world means enlisting HDAudio links as BE
interfaces. Another difference when compared to its DMIC and I2S friends
is lack of NHLT blob usage - no additional hardware configuration is
needed.

Similarly to I2S component, HDA populates its DAIs dynamically, here by
the means of codec->pcm_list_head. Allows for cutting the number of soc
components required to support the interface.
