irqchip/renesas-intc-irqpin: Propagate wake-up settings to parent

The renesas-intc-irqpin 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 r8a7740/armadillo and
sh73a0/kzm9g.

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-intc-irqpin interrupt controller is always cascaded to a
GIC, and the GIC driver always sets SKIP_SET_WAKE since the
aforementioned commit.
