One big Qualcomm Bluetooth schema is hardly manageable: it lists all
possible properties (19 supplies).  Split qcom,qca9377-bt to separate
bindings, so device schema will be easier to read/maintain and list only
relevant properties.

Existing binding has incomplete and incorrect list of supplies (e.g.
there is no VDD_XO) and Linux driver does not ask for any, thus keep
this state unchanged.

My bot found errors running 'make dt_binding_check' on your patch:

yamllint warnings/errors:

dtschema/dtc warnings/errors:


doc reference errors (make refcheckdocs):

See https://patchwork.ozlabs.org/project/devicetree-bindings/patch/20251028-dt-bindings-qcom-bluetooth-v1-3-524a978e3cda@linaro.org

The base for the series is generally the latest rc1. A different dependency
should be noted in *this* patch.

If you already ran 'make dt_binding_check' and didn't see the above
error(s), then make sure 'yamllint' is installed and dt-schema is up to
date:

pip3 install dtschema --upgrade

Please check and re-submit after running the above command yourself. Note
that DT_SCHEMA_FILES can be set to your schema file to speed up checking
your schema. However, it must be unset to test all examples with your schema.
