First their order was wrong by first unloading firmware modules in suspend_late and then taking DSP into reset in suspend_noirq. Second ACPI has put device into OFF state already during suspend_late so trying to reset the DSP is a no-op at suspend_noirq stage. Fix these by moving DSP reset and cleanup into sst_byt_pcm_dev_suspend_late() before firmware unloading.
