[Qemu-arm] [RFC v4 06/27] memory: add IOMMU_ATTR_MSI_TRANSLATE IOMMU memory region attribute

[Eric Auger]

We introduce a new IOMMU Memory Region attribute, IOMMU_ATTR_MSI_TRANSLATE
which tells whether the virtual IOMMU translates MSIs. ARM SMMU
will expose this attribute since, as opposed to Intel DMAR, MSIs
are translated as any other DMA requests.
