dt-bindings: Remove last usage of "binding" or "schema" in titles

The Devicetree bindings document does not have to say in the title that
it is a "Devicetree binding", but instead just describe the hardware.

Most of these have been fixed already, so fix the handful that snuck in.
With this, a meta-schema check can be enabled to catch these
automatically.
