In order to keep the widget use_count balanced, make sure the DAI widgets are allocated once in hw_params and released in hw_free. A 'setup' status flag is used to deal with cases where the .hw_params callback is invoked multiple times, and likewise with cases where hw_free is invoked without hw_params being called first (which can happen if the FE hw_params fails). In addition, this patch frees the widgets in the suspend transition, and reallocates them in the .prepare callback. The 'setup' flag helps in this case differentiate between resume (setup needed) and xruns (setup not needed). This balanced operation was not needed previously but will be required when SOF dynamic pipelines are enabled.
