[PATCH v1 5/8] arm64: dts: qcom: shikra-cqm-evk: Enable sound card support

[Mohammad Rafi Shaik <mohammad.rafi.shaik@oss.qualcomm.com>]

Enable the sound card on the shikra-cqm-evk platform, including
the PM4125 (Rouleur) headset codec, WSA885x external speaker path,
and QAIF backend links.

Also enable the required LPASS macro and SoundWire nodes, along with
the necessary pinctrl configurations for DMIC and I2S interfaces.
