[ Upstream commit c60767421e102dfd1f4d99ad0cc7f8ba24461eb8 ]

The ls-extirq driver doesn't implement the irq_set_wake()
callback, while being wake-up capable. This results in
ugly behaviours across suspend/resume cycles.

Advertise this by adding IRQCHIP_SKIP_SET_WAKE to
the irqchip flags

Fixes: b16a1caf4686 ("irqchip/ls-extirq: Add LS1043A, LS1088A external interrupt support")
