dt-bindings: drop redundant part of title (beginning)

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/' {} \;

find Documentation/devicetree/bindings/ -type f -name '*.yaml' \
-exec sed -i -e 's/^title: [bB]indings\? for \([tT]he \)\?\(.*\)$/title: \u\2/' {} \;

find Documentation/devicetree/bindings/ -type f -name '*.yaml' \
-exec sed -i -e 's/^title: [dD][tT] [bB]indings\? for \([tT]he \)\?\(.*\)$/title: \u\2/' {} \;

dt-bindings: clock: fixed-factor: Drop Allwinner A10 compatible

This compatible is part of the legacy sunxi clock support, and has not
been used since commit 6b48644b1d29 ("ARM: gr8: Convert to CCU") in
October 2016. Now that the code for this compatible has been removed,
let's drop the compatible.

dt-bindings: Remove cases of 'allOf' containing a '$ref'

json-schema versions draft7 and earlier have a weird behavior in that
any keywords combined with a '$ref' are ignored (silently). The correct
form was to put a '$ref' under an 'allOf'. This behavior is now changed
in the 2019-09 json-schema spec and '$ref' can be mixed with other
keywords. The json-schema library doesn't yet support this, but the
tooling now does a fixup for this and either way works.

This has been a constant source of review comments, so let's change this
treewide so everyone copies the simpler syntax.

Scripted with ruamel.yaml with some manual fixups. Some minor whitespace
changes from the script.
