ASoC: SOF: Intel/ipc4: Do not reset BE DAI pipeline

Browse Source 
Merge series from Peter Ujfalusi <peter.ujfalusi@linux.intel.com>:

Do not reset pipelines during the stop/suspend triggers in the BE DAI
ops as the BE DAI pipeline needs to be left in the PAUSED state. It should
only be reset during hw_free. This simplification is already done for
the FE pipelines and the DAI trigger only toggles the states between
PAUSED and RUNNING.
