drm/edid: Add flag to drm_display_info to identify HDMI sinks
The drm_display_info structure contains many fields related to HDMI
sinks, but none that identifies if a sink compliant with CEA-861 (EDID)
shall be treated as an HDMI sink or a DVI sink. Add such a flag, and
populate it according to section 8.3.3 ("DVI/HDMI Device
Discrimination") of the HDMI v1.3 specification.
