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, returning a CPU physical address instead of a port number. Also fix all the drivers that depend on the old behaviour by fetching the CPU physical address based on the port number where it is being needed.
