From: Ranjani Sridharan ranjani.sridharan@linux.intel.com
Add two new fields to save the source widget and sink widget pointers in struct snd_sof_route to make it easier to look up routes by source/sink widget. Also, add a flag to indicate if the route has been set up in the DSP. These will be used when the dynamic pipeline feature is implemented and routes will have to be set up at run time.
Also, add a new sof_tear_down_pipelines() callback, that will used to reset the set up status for all routes during suspend.
