Sebastian Ott bb2b7ffbc4 iommu/s390: simplify registration of I/O address translation parameters
When a new function is attached to an iommu domain we need to register
I/O address translation parameters. Since commit
69eea95c ("s390/pci_dma: fix DMA table corruption with > 4 TB main memory")
start_dma and end_dma correctly describe the range of usable I/O addresses.

Simplify the code by using these values directly.
