[PATCH v3 13/13] drm/i915: replace drm_detect_hdmi_monitor() with drm_display_info.is_hdmi

[Claudio Suarez]

drm_get_edid() internally calls to drm_connector_update_edid_property()
and then drm_add_display_info(), which parses the EDID.
This happens in the function intel_hdmi_set_edid() and
intel_sdvo_tmds_sink_detect() (via intel_sdvo_get_edid()).

Once EDID is parsed, the monitor HDMI support information is available
through drm_display_info.is_hdmi. Retriving the same information with
drm_detect_hdmi_monitor() is less efficient. Change to
drm_display_info.is_hdmi

This is a TODO task in Documentation/gpu/todo.rst
