irqchip/renesas-irqc: Propagate wake-up settings to parent
The renesas-irqc interrupt controller is cascaded to the GIC, but its driver doesn't propagate wake-up settings to the parent interrupt controller. Since commit aec89ef72ba6c944 ("irqchip/gic: Enable SKIP_SET_WAKE and MASK_ON_SUSPEND"), the GIC driver masks interrupts during suspend, and wake-up through gpio-keys now fails on r8a73a4/ape6evm. Fix this by propagating wake-up settings to the parent interrupt controller. There's no need to handle irq_set_irq_wake() failures, as the renesas-irqc interrupt controller is always cascaded to a GIC, and the GIC driver always sets SKIP_SET_WAKE since the aforementioned commit.
