The name should be pci, not pci0.

If you claim the entire 0-255 bus range, I think you should also
specify a domain, otherwise it's not predictable which domain you
get.

The interrupt-map and interrupt-map-mask properties are required for PCI,
otherwise you can't do LSI interrupts.

If your hardware can support it, you should also list I/O space and prefetchable
memory spaces. Can you explain why you have multiple non-prefetchable ranges?
