For dynamic pipelines, We set up the DAI widget during BE DAI hw_params and this results in it getting set up before the scheduler widget for the pipeline it belongs to is set up. Move the scheduler widget set up into sof_widget_setup() to ensure that the scheduler widget is always the first widget in a pipeline to be set up and the last one to get freed after all the other widgets have been freed.
Fixes: 5fcdbb2d45df ('ASoC: SOF: Add support for dynamic pipelines')
