Subject: [PATCH v2 9/9] dt-bindings: mfd: twl: Add missing sub-nodes for TWL4030 & TWL603x

Update the TI TWL family Device Tree binding to include additional
subnodes for TWL4030, TWL6030, and TWL6032 devices.

This patch enhances the schema by adding support for audio, GPIO, power,
keypad, PWM, PWM LED, and USB subnodes, referencing their respective YAML
schemas where applicable. These additions improve the schema's
completeness, enabling better validation and documentation of the
TWL multi-function device's capabilities.

The changes ensure proper handling of TWL4030-specific features (audio,
keypad, PWM, PWM LED, USB, GPIO, and power) and TWL6030/TWL6032-specific
features (PWM, PWM LED, and USB), with appropriate schema references to
prevent unevaluated properties.
