of/promtree: add package-to-path support to pdt
package-to-path is a PROM function which tells us the real (full) name of the
node. This provides a hook for that in the prom ops struct, and makes use
of it in the pdt code when attempting to determine a node's name. If the
hook is available, try using it (falling back to looking at the "name"
property if it fails).
