dw-pcie is used on a lot of systems, I think we should make the common
part of that driver always handle config space in a common way, and
move out the part that parses the ranges property into the individual
soc-specific glue drivers that want to keep optional backwards compatibility
with existing dtbs.

Which one is the other driver?
