board/visionfive2: enable u-boot

Browse Source 
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.
