I rebased my platform MSI, interrupt producer and mbi-gen patch set
on top of yours, and test it on Hisilicon D03 board with SMMv3
enabled, USB and SAS are working properly with configuration
in IORT (yes, I need to add patch from Robin - iommu/arm-smmu: Don't
inadvertently reject multiple SMMUv3s),

Tested-by: Hanjun Guo <hanjun.guo@linaro.org>
