dt-bindings: usb: qcom,pmic-typec: deprecate device-specific VBUS

The Qualcomm PMIC Type-C devices historically provided their own way of
specifying the VBUS regulator, via the device's vdd-vbus-supply node.
This is not ideal as the VBUS is supplied to the connector and not to
the Type-C block in the PMIC. Deprecate this property in favour of the
standard way of specifying it (via the connector's vbus-supply
property).
