Add support for dynamic pipelines by modifying the PCM hw_params ioctl implementation to determine the widgets required for a PCM stream by querying the list of connected DAPM widgets. This list is saved as part of snd_sof_pcm_stream struct and will be used to setup the widgets. The sof_widget_list_setup/free routines setup and free connected DAPM widgets when a PCM is opened/closed. These routines accept a list of connected DAPM widgets as input and determine the SOF widgets, their corresponding pipeline widgets and connections between them that need to be setup before the PCM is triggered. Please note that the dynamic pipeline feature will only be enabled for those pipelines whose dynamic_pipeline_widget flag is set in topologies. Add a new token called SOF_TKN_SCHED_DYNAMIC_PIPELINE that when set in topology will be applied to the dynamic_pipeline_widget flag of the pipeline widget.
