Rework PCM ops callback mechanism

- Fix issues regarding PCM ops callbacks via AVIRT
- As PCMs are created, the PCM ops are set according to the Audio
  Path's needs. A default PCM ops table is applied for all PCMs,
  which includes callbacks such as open, and hw_free, since AVIRT
  requires these for intermediate processing, whether or not a given
  Audio Path may need them.
- Separate PCM ops into separate playback and capture ops tables
