This adds support for a 3D LUT.
The color pipeline now consists of the following colorops:
1. 1D curve colorop
2. Multiplier
3. 3x4 CTM
4. 1D curve colorop
5. 1D LUT
6. 3D LUT
7. 1D curve colorop
8. 1D LUT

This introduces a new drm_colorop_type: DRM_COLOROP_MULTIPLIER.
It's a simple multiplier to all pixel values. The value is
specified via a S31.32 fixed point provided via the
"MULTIPLIER" property.

eason AMD HW hard-codes a PQ
function that is scaled by 125, yielding 80 nit PQ values for
1.0 and 10,000 nits at 125.0.
This patch introduces this scaled PQ EOTF and its inverse as
1D curve types.

The latter one is the one that we want for easy addition and
