The hamoa-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.

---
Changelog:

v2:
  - Changed commit message to explain motivation
  - Removed redundant sound-name-prefix properties for DP0/DP1, since these
    are already defined in the SoC DTSI.
  - v1-link: https://lore.kernel.org/all/20260209091139.622756-1-le.qi@oss.qualcomm.com/

No DP2?

Ideally, these would be sorted alphabetically (so, above 'wcd-foo')
