Subject: [PATCH 1/3] dt-bindings: mtd: move partition binding to its own file
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Single partition binding is quite common and may be:
1. Used by multiple parsers
2. Extended for more specific cases

Move it to separated file to avoid code duplication.
