[PATCH 10/18] ASoC: SOF: sof-audio: Populate the PCM stream pipeline_info

From: Ranjani Sridharan <ranjani.sridharan at linux.intel.com>
Populate the pipeline_info for the PCM stream with the list of pipeline
widgets that need to be handled during the PCM trigger. This will be
used in the IPC-specific PCM trigger op to trigger the pipelines.
