Color Manager framework defines a color correction property for color space transformation and Gamut mapping. This property called CTM (Color Transformation Matrix).
This patch adds a new structure in DRM layer for CTM color correction. This structure will be used by all user space agents to configure CTM coefficients for color correction.
