[00/10] ASoC: Intel: avs: Mute and multi-channel controls support

Note: the patchset DOES provide functional changes to the ASoC
framework.

Current kcontrols loaded with ASoC topology allow for mono or stereo
configuration only. To expand this and provide support to up to 8
channels, first address the limitations found within the ASoC core and
then update the user (avs-driver) so that it can utilize these new
functionality. The 8 channels max stems from SND_SOC_TPLG_MAX_CHAN
constant which is part of UAPI - asoc.h.

For the ASoC side, two changes are made:

- drop the ambiguous usage of ops.info when determining the kcontrol
  type
- save the num_channels value which is already part of the ALSA-topology
  but is currently skipped by ASoC core when loading mixer controls

For the avs-driver side, merge PEAKVOL IPCs as there is basically no
difference between the handles and then do the same with the control
operations. The merge for the latter is done is two steps: first provide
new implementation which honors the multi-channel controls and then move
to it while dropping the now-duplicated code.
