iommu/amd: Initial SVA support for AMD IOMMU This includes : - Add data structure to track per protection domain dev/pasid binding details protection_domain->dev_data_list will track attached list of dev_data/PASIDs. - Move 'to_pdomain()' to header file - Add iommu_sva_set_dev_pasid(). It will check whether PASID is supported or not. Also adds PASID to SVA protection domain list as well as to device GCR3 table. - Add iommu_ops.remove_dev_pasid support. It will unbind PASID from device. Also remove pasid data from protection domain device list. - Add IOMMU_SVA as dependency to AMD_IOMMU driver For a given PASID, iommu_set_dev_pasid() will bind all devices to same SVA protection domain (1 PASID : 1 SVA protection domain : N devices). This protection domain is different from device protection domain (one that's mapped in attach_device() path). IOMMU uses domain ID for caching, invalidation, etc. In SVA mode it will use per-device-domain-ID. Hence in invalidation path we retrieve domain ID from gcr3_info_table structure and use that for invalidation.
