Calling enable_irq_wake() causes suspend_device_irqs() to treat the given IRQ

+in a special way. Namely, the IRQ remains enabled, but on the first interrupt
it will be disabled, marked as pending and "suspended" so that it will be
re-enabled by resume_device_irqs() during the subsequent system resume. Also
the PM core is notified about the event which causes the system suspend in
