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- Dropped ti,am33xx-ecap as it is no longer applicable.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.

-TI SOC ECAP based APWM controller

-Required properties:
-- compatible: Must be "ti,<soc>-ecap".
- for am33xx - compatible = "ti,am3352-ecap", "ti,am33xx-ecap";
- for am4372 - compatible = "ti,am4372-ecap", "ti,am3352-ecap", "ti,am33xx-ecap";
- for da850 - compatible = "ti,da850-ecap", "ti,am3352-ecap", "ti,am33xx-ecap";

- for am654 - compatible = "ti,am654-ecap", "ti,am3352-ecap";
-- #pwm-cells: should be 3. See pwm.yaml in this directory for a description of
- the cells format. The PWM channel index ranges from 0 to 4. The only third
- cell flag supported by this binding is PWM_POLARITY_INVERTED.
-- reg: physical base address and size of the registers map.
-
-Optional properties:
-- clocks: Handle to the ECAP's functional clock.
-- clock-names: Must be set to "fck".

-
-ecap0: ecap@48300100 { /* ECAP on am33xx */
