The BCM2835 ARMCTRL interrupt controller doesn't provide any facility to configure the wakeup sources. That's the reason why this implementation lacks the irq_set_wake implementation. But this prevent us from properly entering power management states like "suspend to idle". So enable the flags IRQCHIP_SKIP_SET_WAKE and IRQCHIP_MASK_ON_SUSPEND to let the irqchip core allows and handles the power management.
