configs/visionfive2_defconfig: new defconfig

Browse Source 
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.

Starfive VisionFive2
====================
The VisionFive2 is a low-cost RISC-V 64-bit based platform, powered by a
Starfive JH7110 processor.
How to build
============
$ make visionfive2_defconfig
$ make
How to write the SD card
========================
Once the build process is finished you will have an image called "sdcard.img"
in the output/images/ directory.
Copy the bootable "sdcard.img" onto an SD card with "dd":
$ sudo dd if=output/images/sdcard.img of=/dev/sdX
Preparing the board
===================
Connect a TTL UART cable to pin 6 (GND), 8 (TX) and 10 (RX).
Insert your SD card.
Power-up the board using an USB-C cable.
