4.18-stable review patch. If anyone has any objections, please let me know.

From: Kai-Heng Feng kai.heng.feng@canonical.com
commit 0711a43b6d84ff9189adfbf83c8bbf56eef794bf upstream.
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.
