We don't know what properties may contain phandles. We might need
something like a generic table of properties that may, along with
corresponding "handler" functions that know how to locate the phandles
within the property to fix them up.

I would recommend not using a linked list for the translation table
though or we'll end up O^2 like hell. We should add some simple hash
table primitive to OPAL.

Cheers,
Ben.
