drm: rcar-du: cmm: Provide 3D-CLU support

The CMM module provides a three-dimensional cubic look up table that
converts three-color-component data into desired three color components
by use of a lookup table.

While the 1D-LUT can only control each of three color components
separately, the 3D-CLU can be used for specific color adjustment.
