The hdmi_colorspace enum was defined to represent the colorspace value of the HDMI infoframes. It was later used by some HDMI drivers to express the output format they should be setting up. During the introduction of the HDMI helpers, it then was used to represent it in the drm_connector_hdmi_state structure. However, it's always been somewhat redundant with the DRM_COLOR_FORMAT_* defines, and now with the drm_output_color_format enum. Let's consolidate around drm_output_color_format in drm_connector_hdmi_state to facilitate the current effort to provide a global output format selection mechanism.
