ENGR00175884 PM: Fix short press gpio power key failed resume system issue
For gpio IRQ which defined as device IRQ is being enabled after syscore resume
completed, this may cause the key down could not be deteced sometime.
Enabel gpio power key early irq during syscore instead of at device resume time.
Some platform like Android need to konw the power key is pressed then to
reume the other devcies
