iommu: Make iommu_queue_iopf() more generic
Make iommu_queue_iopf() more generic by making the iopf_group a minimal set of iopf's that an iopf handler of domain should handle and respond to. Add domain parameter to struct iopf_group so that the handler can retrieve and use it directly. Change iommu_queue_iopf() to forward groups of iopf's to the domain's iopf handler. This is also a necessary step to decouple the sva iopf handling code from this interface.
