irqchip/gic-v3-its: Provide MSI parent infrastructure
To support per device MSI domains the ITS must provide MSI parent domain
functionality.
Provide the basic skeleton for this:
- msi_parent_ops
- child domain init callback
- the MSI parent flag set in irqdomain::flags
This does not make ITS a functional parent domain as there is no bit set in
the bus_select_mask yet, but it provides the base to implement PCI and
platform MSI support gradually on top.
