[PATCH 10/10] ASoC: Intel: avs: Support multi-channel PEAKVOL instantiation

[Cezary Rojewski <cezary.rojewski@intel.com>]

The PEAKVOL module initialization procedure allows for specifying
default configuration for all individual channels. To reflect that in
the code, first update avs_get_module_control() to allow for selecting
Volume or Mute control based on needs and then apply the settings with
newly added avs_peakvol_set_volume() and avs_peakvol_set_mute().
