checkpatch: check proper licensing of Devicetree bindings
According to Devicetree maintainers (see Link: below), the Devicetree
binding documents are preferrably licensed (GPL-2.0-only OR BSD-2-Clause).
Let's check that. The actual check is a bit more relaxed, to allow more
liberal but compatible licensing (e.g. GPL-2.0-or-later OR BSD-2-Clause).
