Subject: [git pull] drm quirk displayport descriptions

Hi Linus,

As mentioned I have a separate request for fixing a regression, but
also keeping the broken hw working, for certain USB-C DP adapters they
require a minimised n/m parameters, but an attempt to do this
generically has failed, we need to quirk these specific adapters.
However doing it generically regressed some eDP panels.

This pull adds the infrastructure and a quirk for the adapter.

Dave.
