[PATCH v2] dt-bindings: mfd: twl: Reference converted schemas for subnodes

[Jihed Chaibi]

Now that all TWL subnode bindings (audio, keypad, twl4030-usb, gpio,
usb-comparator) have been converted and merged into mainline, update the
parent ti,twl.yaml to properly reference them via $ref.

Replace the inline compatible definitions with $ref to the appropriate
schemas and unevaluatedProperties: false, matching the pattern already
used by the madc, gpadc, and charger subnodes.

Changes in v2:
- Drop "YAML" from subject and commit message
- Remove incorrect claim that subnode properties were not being validated
