I'm not sure this is the right way to do it.  Normally, the boot loader
should be able to detect the board revision, and it should dynamically set
the 'status'.  We have other devices that fail if a work-around is not
applied, and we don't use this approach.

But assuming that this really is the best approach, then it would make
sense for --strip-disabled to leave this node in the dtb, because
otherwise there would be no way to re-enable it.
