[PATCH 5/8] docs: dt: Group DT docs into relevant sub-sections

[Rob Herring <robh@kernel.org>]

The DT docs are currently all just lumped together in the doc build.
Let's organize the documents by kernel specifics, overlays and bindings.

As writing-schema.rst is about bindings, let's move it to the bindings
directory.
