From: Ranjani Sridharan <ranjani.sridharan@xxxxxxxxxxxxxxx> When the DSP is suspended while the firmware is in the crashed state, we skip tearing down the pipelines. This means that the widget reference counts will not get to reset to 0 before suspend. This will lead to errors with resuming audio after system resume. To fix this, invoke the tear_down_all_pipelines op before skipping to DSP suspend.
