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.
