[PATCH v1] arm64: dts: qcom: purwa-iot-evk: add missing DP2 audio link

[Le Qi]

The DP2 DAI link is missing from the sound card definition, preventing
audio playback over the third DisplayPort interface.

Add the required codec, CPU, and platform DAI configuration to enable
audio playback over DP2.
