With the platform msi domain created for ITS, irqchip such as
mbi-gen connecting ITS, which needs ctreate its own irqdomain.
Fortunately with the platform msi support upstreamed by Marc,
we just need to add minor code to make it run properly.
platform_msi_create_device_domain() is almost ready for ACPI use
except of_node_to_fwnode() is for dt only, make it ACPI aware then
things will work in both DTS and ACPI.
