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.

This patch touches generic platform-msi code, there is nothing ITS
and mbi-gen specific that has to be known here.

Do you really think that anyone reading this log can easily
make use of this statement ?

This commit log is unreadable and the readable bits do not contain
information that can be used for the purpose a commit log is made
for.

Please rewrite it in a way that can be used in the future to understand
what this patch does and why you want it in the kernel, thanks.
