Subject: [PATCH 5.11 246/775] irqchip/ls-extirq: add IRQCHIP_SKIP_SET_WAKE to the irqchip flags

From: Biwen Li <biwen.li@....com>

[ 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
