[PATCH v4 12/19] irqchip: gicv3-its: Register irq domain with NEXUS token

[Marc Zyngier]

Now that we can distinguish between multiple domains carrying the
same device_node, tag the raw ITS domain with DOMAIN_BUS_NEXUS.
This will allow MSI providers built on top of the raw ITS domain
to identify it.
