dtc: Implement path references
This patch extends dtc syntax to allow references (&label, or
&{/full/path}) directly within property definitions, rather than
inside a cell list. Such references are expanded to the full path of
the referenced node, as a string, instead of to a phandle as
references within cell lists are evaluated.
A testcase is also included.
