[PATCH 14/14] ASoC: Intel: avs: Configure modules according to their type

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

Each module on DSP side serves a processing purpose. Depending on its
purpose, it needs different information during its initialization. Add
functions responsible for creating instances of specific module types
given the information coming from the topology file.
