Subject: [PATCH v2 01/11] iommu/sva: Rename CONFIG_IOMMU_SVA_LIB to CONFIG_IOMMU_SVA
This CONFIG option originally only referred to the Shared
Virtual Address (SVA) library. But it is now also used for
non-library portions of code.
Drop the "_LIB" suffix so that there is just one configuration
options for all code relating to SVA.
