PCI enumeration modifies pci_dev and base_addr at driver initialization therefore these objects move from config_info to driver_data in preparation for config_info becoming const. We drop code that attempts to update irq_num based on PCI enumeration because the interrupt found by PCI enumeration must always be the same as the statically configured IRQ number.
