MLK-18611-2 gpio: mxc: add noirq suspend/resume support
On some i.MX platforms, GPIO banks may lose power
when system suspend, and some peripheral devices
resume may need to use GPIO during resume phase
before GPIO resume, so GPIO needs to be restored
as early as possible, this patch moves GPIO
restore operation to noirq resume phase.
