28ffe8bf90 dt-bindings: Clean-up undocumented compatible strings 
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.
