It has a combined ACPI (via the IORT table) and OF probe path, add iommu_iort_get_single_iommu() to respresent this. It already has a per-instance structure, extend it with the ids[] array and use iommu_fwb_alloc_per_device_ids() to populate it. Convert the rest of the funcs from calling dev_iommu_fwspec_get() to using the per-device data and remove all use of fwspec. Directly call iort_iommu_get_resv_regions() and pass in the internal id array instead of getting it from the fwspec.
