[PATCH 1/4] ASoC: Intel: avs: Add peakvol runtime-parameter requests

[Amadeusz Sławiński <amadeuszx.slawinski@xxxxxxxxxxxxxxx>]

Peakvol module allows for setting and obtaining DSP volume as well as
modifying shape and duration at which volume actually changes. Add IPC
messages to expose those capabilities.
