we want to put created pci device in the device tree as soon as possible. so for_pci_dev will not miss them.
but at that time, we can not load driver for them yet. need to after pci_assign_unsigned_resources etc to make sure all pci devices get resource allocated at first.
so only move adding to device tree early, and leave loading driver on the old places.
