Assuming there is no powergating of the GIC, then this patch should be 
sufficient depending on one question. Whose responsibility is it to 
disable non-wakeup irqs: the interrupt controller code or each driver? 
If drivers are not trusted to disable their interrupt, then GIC 
suspend/resume functions are needed to disable/re-enable non-wakeup irqs.

With powergating of the GIC, saving and restoring of the GIC state in 
addition to external handling of wake-up would be needed.
