of/irq: Document properties for wakeup interrupt parent



Some interrupt controllers in a SoC, are always powered on and have a
select interrupts routed to them, so that they can wakeup the SoC from
suspend. Add wakeup-parent DT property to refer to these interrupt
controllers.

		3) Interrupt wakeup parent
		--------------------------

		Some interrupt controllers in a SoC, are always powered on and have a select
		interrupts routed to them, so that they can wakeup the SoC from suspend. These
		interrupt controllers do not fall into the category of a parent interrupt
		controller and can be specified by the "wakeup-parent" property and contain a
		single phandle referring to the wakeup capable interrupt controller.

		Example:
		wakeup-parent = <&pdc_intc>;
