As with the series as a whole, this might need to change a little bit
if we want to either use devicetree overlays and/or other
architectures.

That being said, I'm okay with having this until then: the only real
topic for bikeshedding is the name.
- Is KUnit best as a board name, or part of the vendor name?
- Do we want to include the architecture in the name?
Should it be "linux,kunit", "linux-kunit,uml", "linux,kunit-uml", etc?
