[PATCH v3 7/7] riscv: dts: starfive: Add StarFive JH7110 VisionFive 2 board device tree

[Hal Feng <hal.feng@starfivetech.com>]

From: Emil Renner Berthing <kernel@esmil.dk>

Add a minimal device tree for StarFive JH7110 VisionFive 2 board
which has version A and version B. Support booting and basic
clock/reset/pinctrl/uart drivers.
