[ Upstream commitde111f6b4f] Commit8e01797331("iommu/amd: Enable Guest Translation before registering devices") moved IOMMU Guest Translation (GT) enablement to early init path. It does feature check based on Global EFR value (got from ACPI IVRS table). Later it adjusts EFR value based on IOMMU feature register (late_iommu_features_init()). It seems in some systems BIOS doesn't set gloabl EFR value properly. This is causing mismatch. Hence move IOMMU GT enablement after late_iommu_features_init() so that it does check based on IOMMU EFR value.
