x86/amd-iommu: Use only per-device dma_ops

commit 27c2127a15d340706c0aa84e311188a14468d841 upstream.

Unfortunatly there are systems where the AMD IOMMU does not
cover all devices. This breaks with the current driver as it
initializes the global dma_ops variable. This patch limits
the AMD IOMMU to the devices listed in the IVRS table fixing
DMA for devices not covered by the IOMMU.
