drm/edid: Fix the HDTV hack.
Standard timings don't let you say 1366. Both 1360 and 1368 have been
seen in the wild. So invent a CVT timing for it. CVT will round 1366 up
to 1368; we'll then manually underscan it.
Split this into two parts, since we need to do something sneaky between
them in the future.
