Now that we introduced a new drm_output_color_format enum to represent what DRM_COLOR_FORMAT_* bits were representing, we can switch to the new enum. The main different is that while DRM_COLOR_FORMAT_ was a bitmask, drm_output_color_format is a proper enum. However, the enum was done is such a way than DRM_COLOR_FORMAT_X = BIT(DRM_OUTPUT_COLOR_FORMAT_X) so the transitition is easier. The only thing we need to consider is if the original code meant to use that value as a bitmask, in which case we do need to keep the bit shift, or as a discriminant in which case we don't.
