Add a driver for the R-Car Display Unit Color Correction Module. In most of Gen3 SoCs, each DU output channel is provided with a CMM unit to perform image enhancement and color correction.
Add support for CMM through a driver that supports configuration of the 1-dimensional LUT table. More advanced CMM feature will be implemented on top of this basic one.

Thanks for your patch!

As they're all handled the same, you can drop the SoC-specific values from the driver's match table.
{ .compatible = "renesas,rcar-gen2-cmm", },
Just wondering: has this been tested on R-Car Gen2?
Gr{oetje,eeting}s,
