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.

iommu/amd: Remove iommu_v2 module
AMD GPU driver which was the only in-kernel user of iommu_v2 module
removed dependency on iommu_v2 module.
Also we are working on adding SVA support in AMD IOMMU driver. Device
drivers are expected to use common SVA framework to enable device
PASID/PRI features.
Removing iommu_v2 module and then adding SVA simplifies the development.
Hence remove iommu_v2 module.
