irqchip: gic: Simplify gic_configure_irq by using IRQCHIP_SET_TYPE_MASKED
GIC requires to disable the interrupt before changing the trigger type.
irqchip core provides IRQCHIP_SET_TYPE_MASKED flag and ensures that the
interrupt is masked before calling chip.irq_set_type() if the irqchip
sets the flag.
This patch adds IRQCHIP_SET_TYPE_MASKED to GIC irqchip so that the core
can manage disabling the interrupt while changing the trigger type.
