Modify memory_get_xlat_addr and vfio_get_xlat_addr to return the memory
region that the translated address is found in. This will be needed by
CPR in a subsequent patch to map blocks using IOMMU_IOAS_MAP_FILE.
Also return the xlat offset, so we can simplify the interface by removing
the out parameters that can be trivially derived from mr and xlat.
Lastly, rename the functions to to memory_translate_iotlb() and
vfio_translate_iotlb().
