- D71 has 3 global layer gamma table which can be used for all layers as gamma lookup table, no matter inverse or forward. - Add komeda_color_manager/state to layer/layer_state for describe the color caps for the specific layer which will be initialized in d71_layer_init, and for D71 only layer with L_INFO_CM (color mgmt) bit can support forward gamma, and CSC. - Update komeda-CORE code to validate and convert the plane color state to komeda_color_state. - Enable plane color mgmt according to layer komeda_color_manager
