ASoC: dt-bindings: qcom,apq8016-sbc-sndcard: move to separate binding

The APQ8016 SBC and MSM8916 QDSP6 sound cards are a bit different from
others: they have additional IO muxing address space and pin control.
Move them to separate schema, so the original qcom,sm8250.yaml will be
easier to manage. New schema is going to grow for other platforms
having more of IO muxing address spaces.
