Convert Qualcomm Audio Stream Manager (Q6ASM) bindings to DT schema. The original bindings documented: 1. APR service node with compatibles: "qcom,q6asm" and "qcom,q6asm-v<MAJOR-NUMBER>.<MINOR-NUMBER>", 2. actual DAIs child node with compatible "qcom,q6asm-dais". The conversion entirely drops (1) because the compatible is already documented in bindings/soc/qcom/qcom,apr.yaml. The "qcom,q6asm-v<MAJOR-NUMBER>.<MINOR-NUMBER>" on the other hand is not used at all - neither in existing DTS, nor in downstream sources - so versions seems to be fully auto-detectable. Another change done in conversion is adding "iommus" property, which is already used in DTS and Linux driver.
