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

[Jihed Chaibi]

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

Previously these subnodes used inline compatible definitions with
additionalProperties: true, which meant properties defined in the
subnode schemas were not being validated. Replace them with $ref to the
appropriate schemas and unevaluatedProperties: false, matching the
pattern already used by the madc, gpadc, and charger subnodes.

subject and here: drop YAML. There are no YAML schemas.

No, they were validated by their child device schemas. Everything was
correct and expected.
