This patch adds Codec2Codec sample to audio-graph-card2-sample.dtsi.
Because it can use very basic connection only for now,
it can use only

	- 2channels
	- S32_LE format

Test-Component driver has "IN" and "OUT" widget. Thus the route is

	+--+
	|  | <-- Codec5
	|  | --> Codec6
	+--+

	(*)
	"IN" -> "DAI5 Capture" -> "DAI6 Playback" -> "OUT"

(*) routing is using "TC" prefix on this sample.

One note here is that it will start works when it boot.
In other words we can't stop it so far.
We need to update driver for it in the future.
