Subject: dtc: Switch dtc to C-style literals

dtc: Switch dtc to C-style literals

This patch introduces a new version of dts file, distinguished from
older files by starting with the special token /dts-v1/.  dts files in
the new version take C-style literals instead of the old bare hex or
OF-style base notation.  In addition, the "range" for of memreserve entries
(/memreserve/ f0000-fffff) is no longer recognized in the new format.
