Add a defconfig for the Starfive VisionFive2 board, a board built around the
Starfive JH7110 RISC-V 64bit SoC.
This board comes with functional lowlevel and U-Boot bootloaders in SPI
flash. The defconfig reuses these and only builds a (5.15 based) kernel and
rootfs.
The factory shipped U-Boot is hard coded to look at MMC partition 3.
