Krzysztof Kozlowski 84e85359f4 dt-bindings: drop redundant part of title (end, part three)
The Devicetree bindings document does not have to say in the title that
it is a "binding", but instead just describe the hardware.

Drop trailing "bindings" in various forms (also with trailing full
stop):

  find Documentation/devicetree/bindings/ -type f -name '*.yaml' \
    -not -name 'trivial-devices.yaml' \
    -exec sed -i -e 's/^title: \(.*\) [bB]indings\?\.\?$/title: \1/' {} \;

title: ST Microelectronics Nomadik I2C
description: The Nomadik I2C host controller began its life in the ST
Microelectronics STn8800 SoC, and was then inherited into STn8810 and
STn8815. It was part of the prototype STn8500 which then became ST-Ericsson
DB8500 after the merge of these two companies wireless divisions.
