We want to add PCI devices to the device tree as early as possible but delay attaching drivers. device_add() adds a device to the device hierarchy and (via device_attach()) attaches a matching driver and calls its .probe() method. We want to separate adding the device to the hierarchy from attaching the driver. This patch does that by adding "match_driver" in struct pci_dev. When false, we return failure from pci_bus_match(), which makes device_attach() believe there's no matching driver. Later, we set "match_driver = true" and call device_attach() again, which now attaches the driver and calls its .probe() method.
