dm: core: Split ofnode_path_root() into two functions
This function turns out to be a little confusing since it looks up a path
and also registers the tree. Split it into two, one that gets the root
node and one that looks up a path, so the purpose is clear.
Registering the tree will happen in a function to be added in a later
patch, called oftree_from_fdt().
