- Set fdt_addr variable, which is needed for extlinux to find FDT. Otherwise booting kernel using extlinux results in missing FDT.
- Also run fdt addr with FDT address so that fdt commands would work out of the box in U-Boot prompt.
This is successfully used by Fedora/RISCV with 5.1-rc3+ kernel using OpenSBI -> U-Boot (S-mode) [extlinux] -> Kernel setup.
