genirq: Add DOMAIN_BUS_NEXUS irqdomain property

Some IRQ domains are not designed to directly provide interrupts
to devices, but strictly to be used by other domains. An example
of this is the GICv3 ITS, which is completely bus agnostic, and
on which it is possible to implement a PCI/MSI domain.

Just introduce the irq_domain_bus_token property for now.
