[PATCH] DTC: Remove the need for the GLR Parser.

[Jon Loeliger <jdl@jdl.com>]

Previously, there were a few shift/reduce and reduce/reduce
errors in the grammar that were being handled by the not-so-popular
GLR Parser technique.

Flip a right-recursive stack-abusing rule into a left-recursive
stack-friendly rule and clear up three messes in one shot: No more
conflicts, no need for the GLR parser, and friendlier stackness.

Both "make check" and the "compare all old and new DTB kernel files"
tests are happy with this change.
