arm64: dts: qcom: sm8750-mtp: Add sound (speakers, headset codec, dmics)
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.
