[RFC PATCH i-g-t 1/5] include/drm-uapi: Add DRM_COLOROP_CSC_FF definition

[Swati Sharma <swati2.sharma@intel.com>]

Add DRM_COLOROP_CSC_FF to the colorop type enumeration. This colorop
type represents a fixed-function Color Space Conversion block where the
coefficients are not programmable but selected from predefined hardware
modes via the CSC_FF_TYPE enum property.

Aligns with kernel commit introducing the CSC Fixed-Function colorop
type for Intel display hardware.
