This was present downstream. Add upstream too.

This applies atop the patch ("arm64: dts: qcom: Add sound node for
sc7180-trogdor-coachz") [1].

NOTE: downstream this property was present in each of the board
revisions. There's actually no longer any reason for this and I'll
shortly post a downstream patch to fix this.
