dt-bindings: bluetooth: qcom,wcn6855-bt: Split to separate schema

One big Qualcomm Bluetooth schema is hardly manageable: it lists all
possible properties (19 supplies).  Split qcom,wcn6855-bt to separate
bindings, so device schema will be easier to read/maintain and list only
relevant properties.
