Add changes to setup display datapath on SC7180 target. Changes in v1: - Add changes to support ctl_active on SC7180 target. - While selecting the number of mixers in the topology consider the interface width.
Changes in v2: - Spawn topology mixer selection into seperate patch (Rob Clark). - Add co-developed-by tags in the commit msg (Stephen Boyd).
