[PATCH 04/18] ASoC: SOF: sof-audio: Only process widgets in the connected widget list

From: Ranjani Sridharan <ranjani.sridharan at linux.intel.com>
When walking the list of the widgets from the source to the sink, we
accidentally also end up preparing/setting up the widgets that are not
in the list of connected DAPM widgets associated with the PCM. Avoid
this by checking if a widget is part of the connected DAPM widget list
during widget prepare, unprepare, setup or free.
