Still missing the "expose the hdmi variant of the prop on lspcon"
part. I didn't include that in my patch since we didn't use
drm_hdmi_avi_infoframe_colorspace() yes on lspcon. Although
maybe I should have just done that change anyway since we were
already registering the prop anyway even if we didn't actually
put the data into the infoframe.
