This is required as every node we use in dts should have the same declared in
dtsi. Sound nodes in most of the platform is only declared (dummy node) in
dtsi and defining only in dts. Thus we are following the same.

Can you point me to Samsung platform doing this?

Keep the code consistent with Exynos style.
