Re: dtc: Implement path references

So, like, the other day David Gibson mumbled:

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.

Excellent.  Very timely! :-)

Applied.
