riscv: dts: allwinner: Add Sipeed Lichee RV devicetrees 



Sipeed manufactures a "Lichee RV" system-on-module, which provides a
minimal working system on its own, as well as a few carrier boards. The
"Dock" board provides audio, USB, and WiFi. The "86 Panel" additionally
provides 100M Ethernet and a built-in display panel.

The 86 Panel repurposes the USB ID and VBUS detection GPIOs for its RGB
panel interface, since the USB OTG port is inaccessible inside the case.
