commit b1186c60aaa0314436f276654ce47281f1ebc41f
Author: Hung-Te Lin 
Date:   Thu Apr 3 21:13:11 2014 +0800

edid: Support EDID 1.4.

EDID v1.4 has changed some fields (0xfc - Monitor Name, 0xfd - Monitor Range
    Limits) to optional so we need to list the requirements explicitly instead of
    sharing v1.3 requirements.
