Subject: [PATCH v3 11/11] dt-bindings: leds: aw200xx: fix led pattern and add reg constraints

AW200XX controllers have the capability to declare more than 0xf LEDs,
therefore, it is necessary to accept LED names using an appropriate
regex pattern.

The register offsets can be adjusted within the specified range, with
the maximum value corresponding to the highest number of LEDs that can
be connected to the controller.

Fixes: e338a05e76ca ("dt-bindings: leds: Add binding for AW200xx")
