Subject: [PATCH v2 10/11] dt-bindings: bluetooth: qcom,wcn7850-bt: Split to
separate schema
One big Qualcomm Bluetooth schema is hardly manageable: it lists all
possible properties (19 supplies). Split qcom,wcn7850-bt to separate
bindings, so device schema will be easier to read/maintain and list only
relevant properties. Re-shuffle few properties to alphabetical order
while moving them and drop redundant enable-gpios description.
This makes the source qualcomm-bluetooth.yaml binding empty, thus drop
it making entire change a variant of file rename.

Changes in v2:
1. Add also Bartosz as maintainer because he was working with this
device in the past.
