Use the common QCOM DAI-node TDM helper to parse the standard DAI TDM slot properties from backend CPU and codec endpoints. Reuse the parsed configuration when programming DAIs so hw_params does not need a second DT traversal. Derive the LPASS backend bit clock from the runtime TDM parameters and request it through the backend child-clock path using LPAIF_MI2S_BCLK. Program codec sysclk in hw_params so codec PLL setup happens before the stream is triggered.
