x86/events/amd/iommu: Enable support for multiple IOMMUs
Add support for multiple IOMMUs to perf by exposing an AMD IOMMU PMU for
each IOMMU found in the system via:
/bus/event_source/devices/amd_iommu_x
where x is the IOMMU index. This allows users to specify different
events to be programmed into the performance counters of each IOMMU.
