Add structures using which user space can set a color pipeline it
desires. The patch introduces two structures
struct drm_color_op_data represents data to be passed
onto individual color hardware blocks.
struct drm_color_pipeline represents the aggregate of drm_color_op_data
structures to program the respective color hardware blocks of the
pipeline. It also contains the pipeline number to be set.
