The skylake driver disabled async suspend to prevent disabling the DSP before the card was suspended during system suspend. This code was carried over to the SOF driver. But, there is no risk of the DSP getting disabled before the card is suspended with the SOF driver. Therefore, it is safe to enable async suspend and thereby optimize the system resume time.
