Convert the existing `lpc32xx-pwm.txt` bindings documentation into a YAML schema (`lpc32xx-pwm.yaml`). Changes: Add SPDX license identifier `(GPL-2.0-only OR BSD-2-Clause)`. Define `$id` and `$schema` fields for proper schema validation. Set `title` to describe the LPC32XX PWM controller. Add maintainers as per `scripts/get_maintainer.pl` output. Reference `pwm.yaml#` in `allOf` to inherit common PWM properties. Define properties: Restrict `compatible` to `"nxp,lpc3220-pwm"` using `const`. Limit `reg` to `maxItems: 1` to ensure a single register range. Set `"#pwm-cells"` to `const: 3` for expected PWM cell properties. Mark `compatible` and `reg` as required properties. Set `unevaluatedProperties: false` to enforce strict validation. Validate the YAML schema using dt-validate and yamllint.
