To prepare for CLU support, expend the CMM API exposed to the DU driver
to separate the LUT table pointer from the LUT update decision. This
will be required, as we will need to update the LUT and CLU
independently.

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 spec

of drm_color_lut3d_mode modes supported by the HW and advertise to

If the driver supports user 3D LUT then it calls a drm function to
attach 3D LUT related properties according to HW caps.

A struct is defined for 3D LUT modes to be supported by hardware.
The elements includes lut_size, lut_stride, bit_depth, color_format
and flags.
Note: A patchset "IGT tests for pre-blending 3D LUT interfaces" for this
proposal is sent to IGT mailing list.

Shaper LUT is used to shape the content after blending, i.e.,
de-linearize or normalize space before applying a 3D LUT color
correction. In the next patch, we add 3D LUT property to DRM color
management after this shaper LUT and before the current gamma LUT.

Add 3D LUT for gammar correction using a 3D lookup table. The position
in the color correction pipeline where 3D LUT is applied depends on hw

be set to shape the content for a non-linear space. That details s
