dtc: Accept NOPs in dtb input regardless of version

[David Gibson]

Since Milton's patch, dtc will accept (and, correctly, ignore) NOP
tags when given dtb input v16 or later.  However, although NOPs
weren't defined in earlier versions, they're not ambiguous, so should
be accepted there as well.  This patch does so, printing a mere
warning when finding NOPs in a too-early dtb version.
