It allows abstraction of hardware color correction and enhancement capabilities by virtue of DRM properties. This patch initializes color management framework by : 1. Introducing new pointers in DRM mode_config structure to carry CTM and Palette color correction properties. 2. Creating these DRM properties in DRM standard properties creation sequence.
