Subject: [PATCH 07/12] dt-bindings: bluetooth: qcom,wcn6750-bt: Split to
separate schema
One big Qualcomm Bluetooth schema is hardly manageable: it lists all
possible properties (19 supplies). Split qcom,wcn6750-bt to separate
bindings, so device schema will be easier to read/maintain and list only
relevant properties.
