The ranges property for a host bridge controller in DT describes
the mapping between the PCI bus address and the CPU physical address.
The resources framework however expects that the IO resources start
at a pseudo "port" address 0 (zero) and have a maximum size of IO_SPACE_LIMIT.
The conversion from pci ranges to resources failed to take that into account.

In the process move the function into drivers/of/address.c as it now
depends on pci_address_to_pio() code and make it return an error code.

I think you're talking about of_pci_range_to_resource().  Can you split
this into one patch that moves it from of_address.h to of/address.c without
changing its functionality, and a second one that does the actual change?
