[Intel-gfx] [PATCH v2 7/9] drm/edid: Unconfuse preferred timing stuff a bit

[Ville Syrjala]

From: Ville Syrjälä <ville.syrjala at linux.intel.com>

For EDID 1.4 the first detailed timing is always preferred,
for older EDIDs there was a feature flag to indicate the same.
While correct, the code setting that up is rather confusing.
Restate it in a slightly more straightforward manner.
