Andrew Lunn dd3cb467eb 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.
