riscv: qemu-riscv.h: define CONFIG_PREBOOT (enables extlinux)
- 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.
