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().
