[PATCH v1] arm64: dts: qcom: purwa-evk: add DP0/DP1 audio playback support

[Le Qi <le.qi@oss.qualcomm.com>]

The purwa-evk DTS currently lacks DAI links for DP0 and DP1, preventing
the sound card from exposing these playback paths. Add the missing links
to enable audio output on both DP interfaces.

This change follows the same approach as the fix for hamoa-evk.
