indicate the interrupts which are currently enabled. This
is to avoid reading interrupt enable register, which varies
on hardware version, for knowing the interrupt enabled info.

It is sometimes observed that afe could send multiple wakeup
events at a time. Avoid this by handling wakeup event only once
per swr suspend.
