Patch from Lennert Buytenhek On the Double Espresso board, the IXP2350s are PCI slave devices and we skip calling pci_common_init() as that enumerates the bus. But even though we are a PCI slave device, there is still some PCI-related setup that has to be done. Create ixp23xx_pci_common_init(), move the common initialisation bits there, and have this function called from both the PCI master and the PCI slave init path.
