Lukas Bulwahn 1a94c18952 iommu/vt-d: include conditionally on CONFIG_INTEL_IOMMU_SVM 
[ Upstream commit 68dd9d89eaf56dfab8d46bf25610aa4650247617 ]

Commit 6ee1b77ba3 ("iommu/vt-d: Add svm/sva invalidate function")
introduced intel_iommu_sva_invalidate() when CONFIG_INTEL_IOMMU_SVM.
This function uses the dedicated static variable inv_type_granu_table
and functions to_vtd_granularity() and to_vtd_size().

These parts are unused when !CONFIG_INTEL_IOMMU_SVM, and hence,
make CC=clang W=1 warns with an -Wunused-function warning.

Include these parts conditionally on CONFIG_INTEL_IOMMU_SVM.

Fixes: 6ee1b77ba3 ("iommu/vt-d: Add svm/sva invalidate function")
