athn_sleep() tries to quiet the chip, athn_resume() powers it up again.
mlelstv suggested that a softint might be in-flight when we suspend,
but we have nothing like softint_wait_inactive() that we could call
after athn_stop in athn_sleep.
Should central sleep code make sure no softints are in flight?
