From: Haibo Chen <haibo.chen@nxp.com>

Add flag IRQCHIP_MASK_ON_SUSPEND to make sure gpio irq is masked on
suspend, if lack this flag, current irq arctitecture will not mask
the irq, and these unmasked gpio irq will wrongly wakeup the system
even they are not config as wakeup source.

Also add flag IRQCHIP_ENABLE_WAKEUP_ON_SUSPEND to make sure the gpio
irq which is configed as wakeup source can work as expect.
