dt-bindings: usb: fusb302: Use usb-connector bindings for configuration
There are now generic usb-connector bindings which can be used to define a port controllers configuration for USB-PD, so device specific bindings are no longer necessary. This update deprecates 'fcs,operating-sink-microwatt', and references the 'usb-connector' bindings instead to achieve the required port config.
