Same DVC might be used few times if system/platform is using MIX.
For example below case.
DAI0 playback = <&src0 &ctu02 &mix0 &dvc0 &ssi0>;
DAI1 playback = <&src2 &ctu03 &mix0 &dvc0 &ssi0>;
This case, ALSA will have DVC,0 and DVC,1 kcontrol interfaces,
but these are same DVC. This is confusable.
Confusing.
This patch adds new flags and avoid such case.

One E is enough. :-)
