drm/edid: Unconfuse preferred timing stuff a bit

Browse Source 
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.
