The Devicetree bindings document does not have to say in the title that
it is a "Devicetree binding", but instead just describe the hardware.
Drop beginning "Devicetree bindings" in various forms:
find Documentation/devicetree/bindings/ -type f -name '*.yaml' \
-exec sed -i -e 's/^title: [dD]evice[ -]\?[tT]ree [bB]indings\? for \([tT]he \)\?\(.*\)$/title: \u\2/' {} \;
