Add Device Tree binding documentation for the Display Control
Unit (DCU) found in Nuvoton MA35D1 SoCs.

The DCU is a DPI-based display controller supporting RGB output
with optional external bridges or panels.

My bot found errors running 'make dt_binding_check' on your patch:

yamllint warnings/errors:

dtschema/dtc warnings/errors:
Documentation/devicetree/bindings/display/nuvoton,ma35d1-dcu.example.dtb: /example-0/display@40260000: failed to match any schema with compatible: ['nuvoton,ma35d1-drm']

doc reference errors (make refcheckdocs):

See https://patchwork.kernel.org/project/devicetree/patch/20260126085727.2568958-2-a0987203069@gmail.com

The base for the series is generally the latest rc1. A different dependency
should be noted in *this* patch.

If you already ran 'make dt_binding_check' and didn't see the above
error(s), then make sure 'yamllint' is installed and dt-schema is up to
date:

pip3 install dtschema --upgrade

Please check and re-submit after running the above command yourself. Note
that DT_SCHEMA_FILES can be set to your schema file to speed up checking
your schema. However, it must be unset to test all examples with your schema.

Thanks, I'll fix the YAML binding issues in the next revision.
