Based on legal's prior response, they are not fixated upon MIT license, so the
BSD-2-Clause license would be fine too; they indicated that even "public domain"
would be fine, except that they don't have a boilerplate header for that, and it's
not suitable since not recognized everywhere, so weren't going to actually
recommend that.

I asked legal about arbitrary files in include/dt-bindings/ in the Linux kernel tree,
so I believe their response is a blanket one for all such files, including [1] below.

For any future similar issues, then Thierry Reding or Jonathan Hunter (both CC'd)
are the people to follow up with. For their context, they can see nvbug 2426449.
