Adding checks for undocumented compatible strings reveals a bunch of warnings in the DT binding examples. Fix the cases which are typos, just a mismatch between the schema and the example, or aren't documented at all. In a couple of cases, fixing the compatible revealed some schema errors which are fixed. There's a bunch of others remaining after this which have bindings, but those aren't converted to schema yet.
