  3. ASoC: dapm: dont delete starting point if list is singular 

    When walking the graph to discover the path from the virtual FE to
the BE, there is only one widget in the path. Do not remove
this BE widget from the list, so it can be used to connect with the
virtual FE dai link.

  4. ASoC: core: set runtime and the cpu_dai/codec_dai active status for v… 

    …irtual dai link

Virtual FE dai links should be manually set to running
state by default with a pcm runtime. The active count of their cpu_dai
and codec_dai's should also be updated. This is required to establish
FE-BE connection and enable the BE DAI when the dpcm runtime is updated.

  5. ASoC: pcm: do not register pcm device for virtual FE dai links 

    Virtual FE dai links do not need to register the pcm device. So
just create the empty pcm device and substream in the
requested direction.

connection to the BE and enable the codec. So make this method
accessible to modules.
