dts: bindings: Remove 'title:' and put all info. into 'description:' Add any useful information from 'title:' to the 'description:' strings (e.g. explanations of acronyms), and remove 'title:' as well as any copy-pasted "this binding gives a ..." boilerplate. Also clean some description strings up a bit. Some other things could probably be cleaned up (replacing 'GPIO node' with 'GPIO controller' on controllers for consistency, for example), but I kept things close to the original to avoid accidentally messing up.

scripts: dts: Simplify and improve 'compatible' matching Instead of properties: compatible: constraint: "foo" , just have compatible: "foo" at the top level of the binding. For backwards compatibility, the old 'properties: compatible: ...' form is still accepted for now, and is treated the same as a single-element 'compatible:'. The old syntax was inspired by dt-schema (though it isn't dt-schema-compatible), which is in turn a thin wrapper around json-schema (the idea is to transform .dts files into YAML and then verify them). Maybe the idea was to gradually switch the syntax over to dt-schema and then be able to use unmodified dt-schema bindings, but dt-schema is really a different kind of tool (a completely standalone linter), and works very differently from our stuff (see schemas/dt-core.yaml in the dt-schema repo to get an idea of just how differently). Better to keep it simple. This commit also piggybacks some clarifications to the binding template re. '#cells:'.
