x86/events/amd/iommu: Add IOMMU-specific hw_perf_event struct
Current AMD IOMMU perf PMU inappropriately uses the hardware struct
inside the union in struct hw_perf_event, extra_reg in particular.
Instead, introduce an AMD IOMMU-specific struct with required parameters
to be programmed into the IOMMU performance counter control register.
Update the pasid field from 16 to 20 bits while at it.
