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).

I understand that there is a consensus on IORT/SMMUv3 specific pieces
of this series while there is some ongoing work on the MBIgen part in
due to dependency on Agustin's patch vs. ACPI definitions.

I think both Agustin's patch set and my mbigen one are in good shape
now if I didn't miss something, Rafael and Lorenzo already acked Agustin's
patch [1-2/3], I provided my review and test tags on them.

And Lorenzo said about the mbigen patches:
"I think this patch (and the FW that goes with it) is wrong, but the rest
of the series, in particular the IORT bits, are ok with me."
and I fixed the wrong patch and updated the _PRS to _CRS as Lorenzo
suggested in v8.

So, can I kindly ask that those patches (Agustin's patch set and my mbigen one)
be merged to 4.11 please? It's really important for Hisilicon (Hip06/Hip07) SoCs
which native NIC [1], SAS [2], USB and even the console on Hip07-D05 drivers
depend on those patches, and those platform are completely dead without
them if PCI is not enabled...

Thanks
Hanjun
