dt-bindings: usb: dwc3: Add support for rk3562

The USB dwc3 core on Rockchip's RK3562 is the same as the one already
included in generic snps,dwc3. Extend the binding accordingly to allow

	compatible = "rockchip,rk3562-dwc3", "snps,dwc3";

There are 4 clocks with different name sequency, add schema for it.
