We typically use same set of distro images (yocto, debian, fedora, etc.)
on both QEMU RISC-V virt machine and SiFive Unleashed board.
With growing kernel and ramdisk images, we need to re-adjust default
U-Boot environment variables. The config header for QEMU RISC-V virt
machine has been already updated to handle bigger kernel and ramdisk
images hence this patch updates SiFive FU540 config header accordingly.
