[COMMON] irqchip: gic: map irq_enable/irq_disable to gic_unmask_irq/gic_mask_irq

It's possible to occur the spurious interrupt from the device.
However, it could be problem when it used for level interrupt.
This patch declares irq_disable to mask_irq in order to prevent
from the spurious interrupts and does irq_enable to unmak_irq
pairly.
