genirq: Set IRQCHIP_SKIP_SET_WAKE for no_irq_chip
If no_irq_chip is used for wake up (e.g. gpio-keys with a simple GPIO controller), the following warning is printed on resume from s2ram: WANING: CPU: 0 PID: 1046 at kernel/irq/manage.c:537 irq_set_irq_wake+0x9c/0xf8() Unbalanced IRQ 113 wake disable This happens because no_irq_chip does not implement irq_chip.irq_set_wake(), causing set_irq_wake_real() to return -ENXIO, and irq_set_irq_wake() to reset the wake_depth to zero. Set IRQCHIP_SKIP_SET_WAKE to indicate that irq_chip.irq_set_wake() is not implemented. Cfr. commit 10a50f1ab5f06c9a ("genirq: Set IRQCHIP_SKIP_SET_WAKE flag for dummy_irq_chip").
