The iommu_sva_domain represents a hardware pagetable that the IOMMU
hardware could use for SVA translation. This adds some infrastructure
to support SVA domain in the iommu common layer. It includes:

The iommu_sva_domain represents a hardware pagetable that the IOMMU
hardware could use for SVA translation. This adds some infrastructure
to support SVA domain in the iommu common layer. It includes:
- Add a new struct iommu_sva_domain and new IOMMU_DOMAIN_SVA domain
type.
- Add a new domain
