iommu: Merge iommu_fault_event and iopf_fault

Browse Source 
The iommu_fault_event and iopf_fault data structures store the same
information about an iopf fault. They are also used in the same way.
Merge these two data structures into a single one to make the code
more concise and easier to maintain.
