Subject: [PATCH v4 1/9] dt-bindings: display: renesas,cmm: Add R-Car CMM documentation

Add device tree bindings documentation for the Renesas R-Car Display
Unit Color Management Module.

CMM is the image enhancement module available on each R-Car DU video
channel on R-Car Gen2 and Gen3 SoCs (V3H and V3M excluded).

This allows 10 valid cases when I imagine there's only really 5. I'm

I imagine there will be a lot of these for Renesas, so just be
consistent.
