[PATCH v7 0/8] Add Intel VT-d nested translation (part 1/2)

This is the first part to add Intel VT-d nested translation based on IOMMUFD nesting infrastructure. As the iommufd nesting infrastructure series[1], iommu core supports new ops to allocate domains with user data. For nesting, the user data is vendor-specific, IOMMU_HWPT_DATA_VTD_S1 is defined for
