Footbridge is the last Arm platform that has its own __virt_to_bus()/__bus_to_virt()/phys_to_dma()/dma_to_phys() abstraction, but this is just a simple offset now. For PCI devices, the offset that is programmed into the PCI bridge must also be set in each device using dma_direct_set_offset(). As Arm does not have a pcibios_bus_add_device() helper yet, just use a bus notifier for this. For the ISA DMA, drivers now pass a non-translated physical address into set_dma_addr(), so they have to be converted back with the corresponding isa_bus_to_virt() function and then into the correct bus address with the offset using the isa_dma_dev.
