[PATCH 2/2] dt-bindings: Remove cases of 'allOf' containing a '$ref'

[Stephen Boyd]

Quoting Rob Herring (2020-04-15 17:55:49)
> 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.
