commit 1a5287a3dbc34cd0c02c8f64c9131bd23cdfe2bb upstream.
During noirq suspend/resume phase, GPIO irq could arrive
and its registers like IMR will be changed by irq handle
process, to make the GPIO registers exactly when it is
powered ON after resume, move the GPIO noirq suspend/resume
callback to syscore suspend/resume phase, local irq is
disabled at this phase so GPIO registers are atomic.
Fixes: c19fdaeea0aa ("gpio: mxc: add power management support")
