[PATCH v5 07/11] 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.

(no changes since v3)
Changes in v3:
- Fix `make W=1 dtbs` warnings (missing reg properties)
- Drop mmc alias
Changes in v2:
- Added DMIC sound card to Lichee RV dock and Lichee RV 86 Panel
- Removed LRADC (depends on analog LDOs)
