[PATCH v2 1/2] dt-bindings: pwm: renesas,tpu-pwm: Improve json-schema

[Geert Uytterhoeven <geert+renesas@xxxxxxxxx>]

  - Include the general PWM controller schema,
  - Make clocks, power-domains, and resets properties required.

Signed-off-by: Geert Uytterhoeven <geert+renesas@xxxxxxxxx>
---
v2:
  - Keep additionalProperties, as pwm.yaml doesn't add any other
    properties.
