[PATCH 05/10] ASoC: Intel: avs: Update VOLUME and add MUTE IPCs

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

For mute kcontrols to have an effect add IPCs for triggering the mute
operation on the DSP side. On top of basic get/set, an aggregated
variant of the latter is provided for both MUTE and, to already present
VOLUME IPC. It allows for efficient transmission of multiple parameters
at once.

While at it, sort the functions - getters come before setters in the
AudioDSP firmware interface as well as in the kcontrol one.
