[Nouveau] [PATCH 15/15] drm/i915: 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. Retriving the same information with
drm_detect_hdmi_monitor() is less efficient. Change to
drm_display_info.is_hdmi where possible.

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

Hmm. Have we parse the EDID by this point actually? I don't think that
was the case in the past but maybe it changed at some point.

FYI there's a third copy of this in intel_dp.c

A helper like this belongs in drm, not i915. Seems useful in other
drivers too.
