The bindings for the V3 Semiconductor PCI bridge are a tad bit outdated and predates the more formal format we have adopted for the bindings. Update them a bit so it is easier to read, and add the Integrator AP- specific compatible so we can detect that we are running on that specific platform. Add a second register bank for the configuration memory area. The device tree specs do specify a memory range for configuration space but it is not applicable to custom accessors like this. Instead follow the pattern from the Versatile PCI adapter and simply add a second register bank for this memory.
