drm/edid: Add 6 bpc quirk for CPT panel in Asus UX303LA

Browse source

commit 06998a756a upstream.

Similar to commit e10aec652f ("drm/edid: Add 6 bpc quirk for display
AEO model 0."), the EDID reports "DFP 1.x compliant TMDS" but it support
6bpc instead of 8 bpc.

Hence, use 6 bpc quirk for this panel.
