U-Boot is often used conjunction with QEMU to boot via EFI or syslinux. Here the QFW boot method is not needed.
At least for qemu-riscv64_smode_defconfig the kernel parameter is used to specify the U-Boot binary. Trying to run U-Boot as a kernel makes no sense.
Provide Kconfig parameter CONFIG_BOOTMETH_QFW to decide if the QFW boot method shall be provided.
