This will be used for NH_VA and NH_VAA commands. It decodes the same fields, trace, calls the UNMAP notifiers and invalidate the corresponding IOTLB entries. At the moment, we do not support 3.2 range invalidation yet. So it reduces to a single IOVA invalidation. Note the leaf bit now is also decoded for the CMD_TLBI_NH_VAA command. At the moment it is only used for tracing.
