Convert APR bindings to yaml format so that we could add new bindings support.
All the dsp services bindings are now part of apr bindings instead
of adding them to audio bindings.

-Qualcomm APR (Asynchronous Packet Router) binding
-
-This binding describes the Qualcomm APR. APR is a IPC protocol for
-communication between Application processor and QDSP. APR is mainly
-used for audio/voice services on the QDSP.
-
-- compatible:
- Usage: required
- Value type: <stringlist>
- Definition: must be "qcom,apr-v<VERSION-NUMBER>", example "qcom,apr-v2"
-
-- qcom,apr-domain
- Usage: required
- Value type: <u32>
- Definition: Destination processor ID.
- Possible values are :
- 1 - APR simulator
- 2 - PC
- 3 - MODEM
- 4 - ADSP
- 5 - APPS
- 6 - MODEM2
- 7 - APPS2
-
-= APR SERVICES
-Each subnode of the APR node represents service tied to this apr. The name
-of the nodes are not important. The properties of these nodes are defined
-by the individual bindings for the specific service
-- All APR services MUST contain the following property:
-
-- reg
- Usage: required
- Value type: <u32>
- Definition: APR Service ID
- Possible values are :
- 3 - DSP Core Service
- 4 - Audio Front End Service.
- 5 - Voice Stream Manager Service.
- 6 - Voice processing manager.
- 7 - Audio Stream Manager Service.
- 8 - Audio Device Manager Service.
- 9 - Multimode voice manager.
- 10 - Core voice stream.
- 11 - Core voice processor.
- 12 - Ultrasound stream manager.
- 13 - Listen stream manager.
-
-- qcom,protection-domain
- Usage: optional
- Value type: <stringlist>
- Definition: Must list the protection domain service name and path
- that the particular apr service has a dependency on.
- Possible values are :
- "avs/audio", "msm/adsp/audio_pd".
- "kernel/elf_loader", "msm/modem/wlan_pd".
- "tms/servreg", "msm/adsp/audio_pd".
- "tms/servreg", "msm/modem/wlan_pd".
- "tms/servreg", "msm/slpi/sensor_pd".
-
-= EXAMPLE
-The following example represents a QDSP based sound card on a MSM8996 device
-which uses apr as communication between Apps and QDSP.
-
- apr {
- compatible = "qcom,apr-v2";
- qcom,apr-domain = <APR_DOMAIN_ADSP>;
-
- apr-service@3 {
- compatible = "qcom,q6core";
- reg = <APR_SVC_ADSP_CORE>;
- };
-
- apr-service@4 {
- compatible = "qcom,q6afe";
- reg = <APR_SVC_AFE>;
-
- dais {
- #sound-dai-cells = <1>;
- dai@1 {
- reg = <HDMI_RX>;
- };
- };
- };
-
- apr-service@7 {
- compatible = "qcom,q6asm";
- reg = <APR_SVC_ASM>;
- ...
- };
-
- apr-service@8 {
- compatible = "qcom,q6adm";
- reg = <APR_SVC_ADM>;
- ...
- };
- };
-
-= EXAMPLE 2
-The following example represents a QDSP based sound card with protection domain
-dependencies specified. Here some of the apr services are dependent on services
-running on protection domain hosted on ADSP/SLPI remote processors while others
-have no such dependency.
-
- apr {
- compatible = "qcom,apr-v2";
- qcom,glink-channels = "apr_audio_svc";
- qcom,apr-domain = <APR_DOMAIN_ADSP>;
-
- apr-service@3 {
- compatible = "qcom,q6core";
- reg = <APR_SVC_ADSP_CORE>;
- };
-
- q6afe: apr-service@4 {
- compatible = "qcom,q6afe";
- reg = <APR_SVC_AFE>;
- qcom,protection-domain = "avs/audio", "msm/adsp/audio_pd";
- ...
- };
-
- q6asm: apr-service@7 {
- compatible = "qcom,q6asm";
- reg = <APR_SVC_ASM>;
- qcom,protection-domain = "tms/servreg", "msm/slpi/sensor_pd";
- ...
- };
-
- q6adm: apr-service@8 {
- compatible = "qcom,q6adm";
- reg = <APR_SVC_ADM>;
- qcom,protection-domain = "avs/audio", "msm/adsp/audio_pd";
- ...
- };
