With platform msi support landed in the kernel, and the introduction
of IORT for GICv3 ITS (PCI MSI) and SMMU, the framework for platform msi
is ready, this patch set add few patches to enable the ACPI platform
msi support.

For platform device connecting to ITS on arm platform, we have IORT
table with the named componant node to describe the mappings of paltform
device and ITS, so we can retrieve the dev id and find its parent
irqdomain (ITS) from IORT table (simlar with the ACPI ITS support).

v8 -> v9:
- Rebased on top of 4.11-rc1 and retest;
- Some of patch's commit message was updated by Lorenzo and
it's clearer (thanks!)

No update in the code, hope it's the final revision.

I will be off the radar till -rc3 but I do not expect major changes
to the series in its current form given that dependencies were merged
in the merge window (ACPI IRQ probe deferral and IORT fixes).

What's your opinion on this patch set? especially for the last 3
patches for mbigen driver, please comment on it to see if I need
to take further steps.

Thanks
Hanjun
