ASoC: dt-bindings: qcom,q6apm-lpass-dais: Split to separate schema

The Qualcomm DSP LPASS Audio DAIs are a bit different than Qualcomm DSP
Audio FrontEnd (Q6AFE) DAIs - they do not use children nodes for each
DAI.  None of other properties from qcom,q6dsp-lpass-ports.yaml apply
here as well, so move the qcom,q6apm-lpass-dais compatible to its own
binding.
