irqchip/ingenic: Leave parent IRQ unmasked on suspend

[ Upstream commit 821fc9e261f3af235752f46e59084467cfd440c4 ]

All the wakeup sources we possibly want will go through the interrupt
controller, so the parent IRQ must not be masked during suspend, or
there won't be any way to wake up the system.
