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.

+Replace drm_detect_hdmi_monitor() with drm_display_info.is_hdmi
+---------------------------------------------------------------
+
+Once EDID is parsed, the monitor HDMI support information is available through
+drm_display_info.is_hdmi. Many drivers still call drm_detect_hdmi_monitor() to
+retrieve the same information, which is less efficient.
+
+Audit each individual driver calling drm_detect_hdmi_monitor() and switch to
+drm_display_info.is_hdmi if applicable.
