Subject: [PATCH 03/12] dt-bindings: bluetooth: qcom,qca9377-bt: Split to
 separate schema

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.
