ASoC: Intel: avs: Fix module lookup

When changing value of kcontrol, FW module to which data should be send
needs to be found. Currently it is done in improper way, fix it. Change
function name to indicate that it looks only for volume module.

This allows to change volume during runtime, instead of only changing
init value.

ASoC: Intel: avs: Parse control tuples

Add callback to handle loading of kcontrol and linking it to active
widget. In order to link kcontrol to specific modules add additional
field to module data, as well as specify control id in kcontrol data.

ASoC: Intel: avs: Add control volume operations

To make introduced peakvol module useful from userspace perspective,
expose ALSA controls allowing DSP volume modification. These provide
even more granular control over volume but are also the only way to
modify volume for devices devoid of codec kcontrols e.g.: DMIC.
