Subject: [PATCH 442/464] dt-bindings: usb: rockchip,dwc3: Add RK3588 binding

RK3588 contains three DWC3 cores. Two of them are connected to
dedicated USBDP PHY and can be used in dual-role. The third is
connected to one of the shared combo PHYs used for PCIe/SATA/USB3
and can only be used in host mode. Since the binding is all about
the PHY glueing and involved clocks, separate compatible values
have been created for these two types.
