Now that there are no more users of path_component_name outside of
the PDT code and users of device_node.full_name are converted to use
"%pOF" printf specifier, we can align Sparc with other arches and store
just the base node name and unit address in full_name. This makes
path_component_name redundant, so it can be removed.
As full_name is used by printf specifiers, set it as early as possible.
