Enables U-Boot and required OpenSBI builds for the VisionFive2. Changes
the sdcard.img to use GPT and adds the SPL and U-Boot to partitions
specified in U-Boot's documentation for the board:
https://docs.u-boot.org/en/v2024.01/board/starfive/visionfive2.html
U-Boot config uses BR2_TARGET_UBOOT_FORMAT_CUSTOM_NAME with value
"u-boot.itb". Using BR2_TARGET_UBOOT_FORMAT_ITB fails, because the
build does not support u-boot.itb make target.

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.
