dt-bindings: pwm: pwm-tiecap: Convert to json schema
Convert the tiecap binding to DT schema format using json-schema.
Along with this conversion the following changes are included:
- 'clock' and 'clock-names' properties are marked required as
driver fails to probe without these properties
- Dropped ti,am33xx-ecap as it is no longer applicable.
- 'power-domains' property is introduced and marked as optional.
