From: Wellenreiter Ethan <Ethan.Wellenreiter@xxxxxxx> [Why] ABGR16161616 colour format was added to dcn10/20/30, and set any ARGB16161616 to the same value as it (26). As such, the HDR10 Green Point y value was too far off of the EDID stated value for DisplayPort. [How] Added back the pixel format as 22 for ARGB16161616 for dcn10/20/30.
