[POWERPC] bootwrapper: Support all-in-one PCI nodes in cuboot-pq2.
Consensus was reached to put PCI nodes at the root of the tree (and not
under /soc), but the phandle to a control node was rejected in favor of
simply not worrying about /pci/reg overlapping /soc/ranges.
This updates cuboot-82xx to not look for the phandle.
