PCI: call final fixups hot-added devices
Final fixups are currently applied only at boot-time by pci_apply_final_quirks(), which is an fs_initcall(). Hot-added devices don't get these fixups, so they may not be completely initialized. This patch makes us run final fixups for hot-added devices in pci_bus_add_device() just before the new device becomes eligible for driver binding. This patch keeps the fs_initcall() for devices present at boot because we do resource assignment between pci_bus_add_device and the fs_initcall(), and we don't want to break any fixups that depend on that assignment. This is a design issue that may be addressed in the future -- any resource assignment should be done *before* device_add().
