[PATCH 2/2] arm64: dts: qcom: sm8750-mtp: Add sound (speakers, headset codec, dmics)

[Krzysztof Kozlowski <krzysztof.kozlowski@linaro.org>]

Add device nodes for most of the sound support - WSA883x smart speakers,
WCD9395 audio codec (headset) and sound card - which allows sound
playback via speakers and recording via DMIC microphones.  Changes bring
necessary foundation for headset playback/recording via USB, but that
part is not yet ready.
