irqdomain: Add parent field to struct irqchip_fwid
The GICv5 driver IRQ domain hierarchy requires adding a parent field to
struct irqchip_fwid so that core code can reference a fwnode_handle parent
for a given fwnode.
Add a parent field to struct irqchip_fwid and update the related kernel API
functions to initialize and handle it.
