ALSA: PCM: volume API implementation
Introduced a new helper function snd_pcm_add_volume_ctls() to
create control elements representing the volume for each PCM
(sub)stream.
This patch also squashes the logic implemented by below change-
ASoC: Fix freed memory access of pcm stream kctl
Consider sound card instantiate fails due to
audrx init failure. In such case, all dais/ctls
are de-registered and freed. But as part of it,
access to unregistered ctls for pcm_chmap and similar
controls result in crash. Ctls are freed at disconnection
but the disconnect is called only when it was registered.
