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'.
