dts changes and backwards compatibility are ultimately up to the
platform maintainers. Your users can yell at you if they care. I only
ask that changes that break compatibility are documented as doing so.

Personally, I'm in favor of this change. I'd rather seem uniformity
across boards and this is just a dev board and LED functions won't
affect booting.
