usb: msm_otg: Don't enable OTG IRQ for wakeup if ASYNC IRQ is used

On targets that use a dedicated async wakeup interrupt, the OTG
IRQ is not used for triggering wakeup from deep low power mode.
Hence, change the logic so that one or the other, but not both,
is used when calling enable/disable_irq_wakeup().
