[PATCH v4 2/2] arm64: dts: qcom: talos-evk: Add sound card support with DA7212 codec

[Le Qi]

Add the sound card node for QCS615 Talos EVK with DA7212 codec
connected over the Primary MI2S interface. The configuration enables
headphone playback and headset microphone capture, both of which have
been tested to work.
