Commit6ee1b77ba3("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.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
