msm:disp:dpu1: setup display datapath for SC7180 target

Browse Source 
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 separate patch (Rob Clark).
 - Add co-developed-by tags in the commit msg (Stephen Boyd).

Changes in v3:
 - Fix kernel checkpatch errors in v2.

This patch has dependency on the below series
