ASoC: SOF: sof-audio: Set up widgets from source to sink
For IPC3, the order of setting up the widgets associated with a PCM
doesn't matter. But for IPC4, widgets must be set up from the source to
the sink in order. In order to accommodate this, change the
sof_widget_list_setup/free() functions to set up/free widgets starting
with the source widget all the way to the sink widget for all pipelines.
