This block contains a map of indexes of CEA modes, which can support YCBCR 420 output also. To avoid multiple parsing of same CEA block, let's parse the sink information and get this map, before parsing CEA modes. This patch moves the call to drm_add_display_info function, before the mode parsing block.
