dt-bindings: bluetooth: qcom,qca2066-bt: Split to separate schema

One big Qualcomm Bluetooth schema is hardly manageable: it lists all
possible properties (19 supplies).  Split common part and
qcom,qca2066-bt to separate bindings, so each schema will be easier to
read/maintain and list only relevant properties.

The existing bindings do not mention interrupts, but
am335x-sancloud-bbe-extended-wifi.dts already defines such.  This issue
is not being fixed here.

Existing binding also did not mention any supplies (which do exist as
confirmed in datasheet) and Linux driver does not ask for any, thus keep
this state unchanged.
