arm64: dts: rockchip: Enable all 3 USBs on Turing RK1

The Turing RK1 contains 3 different USBs:
- USB0: USB 2.0, OTG
- USB1: USB 3.0, host
- USB2: USB 2.0, host

This patch activates the necessary DT nodes to enable all 3 buses.

Future work will be needed on USB0: it is not USB3-capable, so the USB0
controller needs to be told that there is no USB3 port. Per Jonas's
suggestion, the USBDP0 node is given a `rockchip,dp-lane-mux` property
that tells the USBDP driver that USBDP0 is not involved in USB so that
it can make the necessary configuration changes in hardware.
Technically, this is USB *controller* configuration, not *PHY*
configuration, so the underlying code may be moved in the future to the
USB controller driver instead, freeing up the (software) dependency on
USBDP0. A TODO comment is added to explain this.
