[PATCH v1 2/2] arm64: dts: qcom: eliza-cqs-evk: Enable sound card support with WSA8845 and DMIC

[Ravi Hothi <ravi.hothi@oss.qualcomm.com>]

Enable the sound card on the Eliza CQS EVK platform, including the
WSA8845 external speaker path and DMIC microphone capture via VA macro.

Enable the required LPASS WSA macro, VA macro and SoundWire controller
along with the necessary pinctrl configurations for DMIC and WSA
SoundWire interfaces.
