WKUP_ALERT interrupt should be unmask when lpm mode is enabled. This interrupt is asserted when the device is in L1 for the duration mentioned in GREFCLK.SOF_CNN_WKUP_ALERT. This is used to alert SW to initiate Remote wake up so that the device resumes in time in order not to lose sync with the host frame number.
