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.
