[PATCH v2 05/14] ASoC: Intel: avs: Parse pipeline and module tuples

Shape of a path on DSP side, that is, the number and the layout of its
pipelines and modules is paramount for streaming to be efficient and low
power-consuming. Add parsing helpers to support loading such information
from the topology file.
