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.
