Subject: [PATCH] x86/events/amd/iommu: Make symbol 'amd_iommu_attr_groups' static

Fix the following sparse warning:

arch/x86/events/amd/iommu.c:396:30: warning:
 symbol 'amd_iommu_attr_groups' was not declared. Should it be static?

Fixes: 51686546304f (x86/events/amd/iommu: Fix sysfs perf attribute groups)
