Framebuffer formats P01x are supported by GLK, but the function which handles CSC on plane color control register, still expectes the input buffer to be REC709. This can cause inaccurate output for direct P01x flips. This patch checks if the color_encoding property is set to YCBCR_2020, and enables the corresponding color conversion mode on plane CSC. PS: renamed variable plane_color_ctl to color_ctl for 80 char stuff. V2: Expose the YCBCR_BT2020 value in enum values of supported encoding formats.
