Convert the legacy TXT binding for the TWL-family PWMLED controller
to the modern YAML DT schema format. This adds formal validation
and improves documentation by inheriting from the base pwm schema.

-Supported PWMs:
-On TWL4030 series: PWMA and PWMB (connected to LEDA and LEDB terminals)
-On TWL6030 series: LED PWM (mainly used as charging indicator LED)
-
-Required properties:
-- compatible: "ti,twl4030-pwmled" or "ti,twl6030-pwmled"
-- #pwm-cells: should be 2. See pwm.yaml in this directory for a description of
- the cells format.
