The APR/GPR nodes are organized like:

  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]) already grows
considerably 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.

Simplify the qcom,apr.yaml by splitting the services to a shared file
which will be:
1. Referenced by qcom,apr.yaml with additionalProperties:true,
2. Referenced by specific bindings for services with
   additionalProperties:false (not yet in this commit).

While moving the code, add also required 'reg' and
'qcom,protection-domain' to further constrain the bindings.
