I think when we say irq_wake_enable() then based on underlying HW, it 
should not turn off the irq if it is require for the wakeup. I mean it 
need to be handle in the hw specific callbacks to keep enabling the 
wakeup irq on suspend also.
For me, I have key which is interrupt based from PMIC, not based on GPIO 
and on that if I set it to IRQF_EARLY_RESUME then it works fine.
