pci device for hotplug have same problem. need to delay driver attach for them too.
also BUS_ADD_MATCH and BUS_ADD_START are duplicated.
old add are separated to adding all devices to tree and then matching work to load the drivers.
so _START is not needed anymore, only user.start in pci_root driver should be removed. code in .start could be moved .add without problem.
