[PATCH v2] dt-bindings: arm: st,nomadik: Convert to DT schema

[Andrew Rembrandt]

Convert the ST Nomadik boards binding from free-form text to DT schema.

The binding documents the Nomadik NHK15/USB-S8815 platform compatibles.

Changes since v1:
- Replace 'oneOf'+'const' with 'enum'
- Remove example node (per Conor Dooley's review - it had no corresponding node
  in the relevant dts files)

Thanks to Conor Dooley, Rob Herring, & Linus Walleij for the reviews.
