HDMI port voltage swing programming workaround.
By default, each HDMI port in Kaby Lake display engines uses the voltage
swing setting specified when the port is first enabled. A new voltage swing
setting can be programmed by setting this field to 3 (0b11) right before
setting the `enabled` field in the DdiBufferControl register, waiting for
1us, and then setting this field to zero (0b00).
This field is scoped to DDIs, not to transcoders. GetForKabyLakeDdi() will
return the correct register for applying this workaround to a DDI.
