VisionFive 2: Add default device tree overlay addressVF2_v3.0.4
This is needed for device tree overlays to work when adding them via "fdtoverlays /path/to/overlay.dtbo" to extlinux.conf.
Of course this can be also set in uEnv.txt, but this U-Boot build reads that environment file from partition 3 with FAT filesystem only, which makes this an unnecessary limitation. Also, this variable is listed as mandatory in upstream U-Boot docs: https://github.com/u-boot/u-boot/blob/master/doc/develop/distro.rst#required-environment-variables
To allow using device tree overlays on the VisionFive 2, including the one shipped with StarFive's own kernel build, via extlinux in a generic and upstream-compatible way, this variable is hereby added.
The used address is sufficiently distant from the initramfs address, also in case 0x48100000 is used (override via uEnv.txt in StarFive's Debian image).
