IB/core: Restore I/O MMU, s390 and powerpc support
Avoid that the following error message is reported on the console while loading an RDMA driver with I/O MMU support enabled: DMAR: Allocating domain for mlx5_0 failed Ensure that DMA mapping operations that use to_pci_dev() to access to struct pci_dev see the correct PCI device. E.g. the s390 and powerpc DMA mapping operations use to_pci_dev() even with I/O MMU support disabled. This patch preserves the following changes of the DMA mapping updates patch series: - Introduction of dma_virt_ops. - Removal of ib_device.dma_ops. - Removal of struct ib_dma_mapping_ops. - Removal of an if-statement from each ib_dma_*() operation. - IB HW drivers no longer set dma_device directly.
