[ Upstream commit de2942828e7670526289f098df7e50b112e8ff1e ]
The interrupt controller found on RZ/G3E doesn't provide any facility to configure the wakeup sources. That's the reason why the driver lacks the irq_set_wake() callback for the interrupt chip.
But this prevent to properly enter power management states like "suspend to idle".
Enable the flags IRQCHIP_SKIP_SET_WAKE and IRQCHIP_MASK_ON_SUSPEND so the interrupt suspend logic can handle the chip correctly.
