The example for PCI devices has some addressing errors. 'reg' is written as if the parent bus is PCI, but the default bus for examples is 1 address and size cell. 'ranges' is defining config space with a size of 0. Generally, config space should not be defined in 'ranges', only PCI memory and I/O spaces. Fix these issues by updating the values with made-up, but valid values. This was uncovered with recent dtschema changes.
