[PATCH 4/4] DTC: Begin the path to sane literals and expressions.

[Jon Loeliger]

So, like, the other day Segher Boessenkool mumbled:

Are any of those property names in use in any
of our DTS files or b-w-o.txt?  Not really, no.
In fact, with this lexical change, all of our
DTS files still produce byte-identical results.

I really think this is one of those areas where
we may need to stray from the other guideline.

Is there a compelling reason somewhere?  Really?
