Subject: [PATCH 2/2] arm64: dts: qcom: sm8550-mtp: add WCD9385 audio-codec

Add Qualcomm Aqstic WCD9385 audio codec on two Soundwire interfaces: RX
and TX.

Signed-off-by: Krzysztof Kozlowski <krzysztof.kozlowski@...aro.org>

---

Not tested and not really verified against schematics (no access).
MTP added based on downstream DTS.
