Subject: drm/edid: Add 6 bpc quirk for BOE panel in HP Pavilion 15-n233sl
Git-commit: 0711a43b6d84ff9189adfbf83c8bbf56eef794bf
Patch-mainline: v4.19
References: bsc#1113722

There's another panel that reports "DFP 1.x compliant TMDS" but it
supports 6bpc instead of 8 bpc.

Apply 6 bpc quirk for the panel to fix it.
