For "freeze" mode of suspend, cpu will go into idle and
those wakeup sources' irq should NOT be disabled during
devices suspend, so we need to add IRQF_NO_SUSPEND flag
for those wakeup sources.
Steps to test this patch:
1. echo freeze > /sys/power/state;
2. press gpio key which has wakeup function, then system
will resume.
