-Qualcomm Audio Stream Manager (Q6ASM) binding
-
-Q6ASM is one of the APR audio service on Q6DSP.
-Please refer to qcom,apr.txt for details of the common apr service bindings
-used by the apr service device.

-- but must contain the following property:
-
-- compatible:
- Usage: required
- Value type: <stringlist>
- Definition: must be "qcom,q6asm-v<MAJOR-NUMBER>.<MINOR-NUMBER>".
- Or "qcom,q6asm" where the version number can be queried
- from DSP.
- example "qcom,q6asm-v2.0"

-= ASM DAIs (Digial Audio Interface)

-== ASM DAI is subnode of "dais" and represent a dai, it includes board specific
-configuration of each dai. Must contain the following properties.
-
-- reg
- Usage: required
- Value type: <u32>
- Definition: Must be dai id
-
-- direction:
- Usage: Required for Compress offload dais
- Value type: <u32>
- Definition: Specifies the direction of the dai stream
- Q6ASM_DAI_TX_RX (0) for both tx and rx
- Q6ASM_DAI_TX (1) for only tx (Capture/Encode)
- Q6ASM_DAI_RX (2) for only rx (Playback/Decode)
-
-- is-compress-dai:
- Usage: Required for Compress offload dais
- Value type: <boolean>
- Definition: present for Compress offload dais

DSP Audio Strem bindings have been documented with DSP services bindings which makes it difficult to reuse them, so pull them out in to a dedicated bindings. Also as part of this change convert them into yaml format. This patch also removes q6asm bindings as dsp services are now documented in apr bindings.
