PCI: Make pci_setup_bridge() non-static for use by arch code
The "powernv" platform of the powerpc architecture needs to assign PCI resources using a specific algorithm to fit some HW constraints of the IBM "IODA" architecture (related to the ability to create error handling domains that encompass specific segments of MMIO space). For doing so, it wants to call pci_setup_bridge() from architecture specific resource management in order to configure bridges after all resources have been assigned. So make it non-static.
