Add support for DSP volume controls
Merge series from Amadeusz Sławiński <amadeuszx.slawinski@linux.intel.com>: Some devices like DMIC don't expose native controls or need volume limit due to possible HW damage. Add support for volume controls allowing to change volume level in DSP. Maximum volume level is imposed by the topology file which defines given path.
