arm64: dts: rockchip: Enable USB device mode on rk3588s-roc-pc
The USB3 OTG controller on the ROC-PC can be used in device mode,
but the board description only enabled the DWC3 controller and USB2 PHY.
The USBDP PHY remained disabled and the controller had no role-switch
default, so DWC3 did not register a UDC and USB gadget drivers such
as g_mass_storage failed to bind.
Enable the USBDP PHY and describe the controller as a USB role switch
with peripheral as the default role. This lets the controller register
as a UDC when no external role provider has selected a host role.
Tested on a Firefly Station M3 by binding g_mass_storage to expose the
eMMC as a USB mass-storage gadget.
