Chaitanya Kumar Borah f6c58e4ae8 drm/colorop: Add DRM_COLOROP_FIXED_MATRIX
Introduce DRM_COLOROP_FIXED_MATRIX, a new colorop type representing a
hardware that performs a fixed matrix operation.

Unlike CTM-based colorops, this block does not expose programmable
coefficients. Instead, userspace selects one of the predefined
hardware modes via a new FIXED_MATRIX_TYPE enum property. Supported modes
include common YCbCr->RGB and RGB709->RGB2020 conversions.

v5:
 - Drop YCbCr limited to full and RGB709 to RGB2020 matrices
   until we have non-IGT userspace that shows their use (Robert)

v4:
 - Add limited-range YCbCr-RGB conversion matrix enums (Robert)
 - Document matrix values (Pekka)
 - Clarify RGB709 to RGB2020 is a full-range matrix (Pekka)
 - Fix confusing "CSC preset" doc (Pekka)

v2:
 - Naming changes (Pekka)

v3:
 - Fix NC matrix enum name and string (Melissa)
 - Rebase
