Add changes to setup display datapath on SC7180 target
changes in v1:
1) add changes to support ctl_active on SC7180 target
2) while selecting the number of mixers in the topology
consider the interface width.

could you spit this fix into it's own patch (and I guess s/User/Use/
in the comment
I guess width > 1080 actually works ok? IIRC mdp5 switched to split
at 2k. Or is it advantages to use split path (with presumably lower
clocks)? I wonder if there are scenarios where we want to use split
topology unless there is an external display connected, or depending
on the resolution of the external display?

could you spit this fix into it's own patch (and I guess s/User/Use/
in the comment
I guess width > 1080 actually works ok? IIRC mdp5 switched to split
at 2k. Or is it advantages to use split path (with presumably lower
clocks)? I wonder if there are scenarios where we want to use split
topology unless there is an external display connected, or depending
on the resolution of the external display?

could you spit this fix into it's own patch (and I guess s/User/Use/
in the comment
I guess width > 1080 actually works ok? IIRC mdp5 switched to split
at 2k. Or is it advantages to use split path (with presumably lower
clocks)? I wonder if there are scenarios where we want to use split
topology unless there is an external display connected, or depending
on the resolution of the external display?
