 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?
