[PATCH V3 3/4] irqchip/loongson-pch-pic: Support to set irq type for ACPI path

[Jianmin Lv]

For ACPI path, the translate callback used IRQ_TYPE_NONE and ignored
the irq type in fwspec->param[1]. For supporting to set type for
irqs of the irqdomain, fwspec->param[1] should be used to get irq
type.
