[PATCH v2] dt-bindings: thermal: rcar-thermal: Improve schema validation

[Geert Uytterhoeven <geert+renesas@xxxxxxxxx>]

  - Document missing "#thermal-sensor-cells",
  - Factor out common required properties,
  - "interrupts", "clocks", and "power-domains" are required on R-Mobile
    APE6, too,
  - Invert logic to simplify descriptions,
  - Add "additionalProperties: false".
