Series x86: Add single 64-bit U-Boot without SPL for QEMU |

  From: Simon Glass <simon.glass@canonical.com>

Add a defconfig for QEMU x86_64 that builds a single 64-bit
binary with integrated 16-bit and 32-bit startup code, removing
the need for SPL.

The existing SPL-based qemu-x86_64 build is unaffected.
