From: Ville Syrjälä <ville.syrjala@xxxxxxxxxxxxxxx>
intel_hdmi.has_hdmi_sink is tied into the force audio property, so it
doesn't seem like the correct way to detect HDMI monitors. Instead add
a new has_hdmi_monitor member which simply tells whether a HDMI monitor
was detected.
Not sure if this is the best way, or if we should just use has_hdmi_sink
for the CEA-861 automatic color range property... At least the infoframe
stuff already depends on has_hdmi_sink.
