Jon Derrick 2856ba6020 PCI: Introduce pci_real_dma_dev()
The current DMA alias implementation requires the aliased device be on the
same PCI bus as the requester ID.  Add an arch-specific mechanism to point
to another PCI device when doing mapping and PCI DMA alias search.  The
default case returns the actual device.
