dt-bindings: net: add compatible strings for lan969x targets

Add compatible strings for the twelve different lan969x targets that we
support. Either a sparx5-switch or lan9691-switch compatible string
provided on their own, or any lan969x-switch compatible string with a
fallback to lan9691-switch.

Also, add myself as a maintainer.
