irqchip/loongson-liointc: Add IRQCHIP_SKIP_SET_WAKE flag

LIOINTC doesn't require specific logic to work with wakeup IRQs,
and no irq_set_wake callback is needed. To allow registered IRQs
from LIOINTC to be used as a wakeup-source, and ensure irq_set_irq_wake()
works well, the flag IRQCHIP_SKIP_SET_WAKE should be added.
