[PATCH v2 3/5] riscv: dts: thead: add sipeed Lichee Pi 4A board device tree

From: Jisheng Zhang <jszhang@kernel.org>

Sipeed's Lichee Pi 4A development board uses Lichee Module 4A core
module which is powered by T-HEAD's light(a.k.a TH1520) SoC. Add
minimal device tree files for the core module and the development
board.

Support basic uart/gpio/dmac drivers, so supports booting to a basic
shell.
