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

Commit Message

Amadeusz Sławiński Dec. 14, 2022, 6:54 p.m. UTC

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.
