Does it actually or do we just ignore the fact that it reports 3.24Gbps?
If it really reports 3.24 then we should be able to just add that to
dp_rates[] in intel_dp_set_sink_rates() and be done with it.
Although we'd likely want to skip 3.24 unless it really is reported
as the max so as to not use that non-standard rate on other displays.
So would require a bit fancier logic for that.
Was also my initial thought, but the DP_MAX_LINK_RATE reg reports 2.7 Gbps as maximum.
