ASoC: dt-bindings: qcom,apr: Correct and extend example

Correct the APR/GPR example:
1. Use consistent 4-space indentation,
2. Add required properties to services nodes, so the binding check
   passes once schema for these services is improved,
3. Add few other properties as APR/GPR is part of a GLINK edge:
   qcom,glink-channels and qcom,intents.
4. Drop unnecessary services, to make the example compact.
