drm/edid: use DC flags to indicate deep color support

DRM EDID parser is using same flags to indicate RGB/YCBCR444 support
and also to indicate deep color support for RGB/YCBCR444 formats.
Use DC flags like
DRM_COLOR_FORMAT_DC_RGB444 instead of DRM_COLOR_FORMAT_RGB444
DRM_COLOR_FORMAT_DC_YCRCB444 instead of DRM_COLOR_FORMAT_YCRCB444
to indicate DC support.
