This is after the pipe gamma block and is in addition to the legacy pipe CSC block. Primary use case for this block is to convert RGB to YUV in case sink supports YUV. This patch adds supports for the same. v2: This is added after splitting the existing ICL pipe CSC handling. As per Matt's suggestion, made this to co-exist with existing pipe CSC, wherein both can be enabled if a certain usecase arises. v3: Fixed an issue with co-existence of output csc and normal pipe csc, spotted by Matt. Put the csc mode flag enabling to color_check to align with atomic. v4: Fixed macro alignment and checkpatch complaints wrt line over 100 characters limit.
