iommu/vt-d: Remove intel_svm_dev
The intel_svm_dev data structure used in the sva implementation for the
Intel IOMMU driver stores information about a device attached to an SVA
domain. It is a duplicate of dev_pasid_info that serves the same purpose.
Replace intel_svm_dev with dev_pasid_info and clean up the use of
intel_svm_dev.
