dt-bindings: Remove 'Device Tree Bindings' from end of title:

As indicated in
link: https://lore.kernel.org/all/20220822204945.GA808626-robh@kernel.org/

DT schema files should not have 'Device Tree Binding' as part of there
title: line. Remove this in most .yaml files, so hopefully preventing
developers copying it into new .yaml files, and being asked to remove
it.

matching Device Tree binding.

Now that we have the DT validation in place, let's convert the device tree
bindings for that controller over to a YAML schemas.
