ASoC: dt-bindings: Rework Qualcomm APR/GPR Sound nodes for SM8450

Merge series from Krzysztof Kozlowski <krzysztof.kozlowski@linaro.org>:

Adding sound support for Qualcomm SM8450 SoC (and later for SC8280XP) brought
some changes to APR/GPR services bindings.  These bindings are part of
qcom,apr.yaml:

  apr-or-gpr-device-node <- qcom,apr.yaml
    apr-gpr-service@[0-9] <- qcom,apr.yaml
      service-specific-components <- /schemas/sound/qcom,q6*.yaml

The schema for services (apr-gpr-service@[0-9]) was not complete and is still
quite not specific.  It allows several incorrect combinations, like adding a
clock-controller to a APM device.  Restricting it would complicate the schema
even more.  Bringing new support for sound on Qualcomm SM8450 and SC8280XP SoC
would grow it as well.

Refactor the bindings before extending them for Qualcomm SM8450 SoC.
