This registers the memory ranges for I/O, non-prefetched and prefetched memory and configuration space for the PCIv3 bridge and let us fetch these basic memory resources from the device tree in the device tree boot path. Remove the stepping stone platform device. This is an either/or approach - the platform data path is mutually exclusive to the plain platform data path and provided addresses from the device tree have to be correct. This adds the interrupt-map property to the PCIv3 DTS file and makes the bridge obtain mappings from the device tree.
