edid: add hdmi_monitor_detected in data struct edid

HDMI driver need to know whether the monitor is DVI
    or HDMI interface, so this commit just introduce a
    new number 'hdmi_monitor_detected' to struct edid.

There were four bits to indicate the monitor interfaces,
    it's better to take use of that. But those bits only
    existed in EDID 1.4 version, but didn't persented in
    the previous EDID version, so I decided to detect the
    hdmi cea block.

BRANCH=none
    BUG=chrome-os-partner:43789
    TEST=When mickey connect with HDMI monitor, see 'hdmi_monitor_detected' is 'true'.
         When mickey connect with DVI monitor, see 'hdmi_monitor_detected' is 'false'.
