Subject: u-boot: arm64: Save our modifications to the upstream defconfigs

Run diffconfig from Linux to track our modifications to the old upstream
defconfigs, so we can apply them to the new ones. Restore the original
defconfigs to highlight our changes here, and upstream changes in the
next commit. Done manually, but something like:

  do_diff() {
      ours="$1"
      theirs="$2"
      tree="$3"

      diffconfig \
          src/u-boot/${tree}/configs/${theirs}_defconfig \
          config/u-boot/${ours}/config/default \
          >config/u-boot/${ours}/config/diffconfig

      cp src/u-boot/${tree}/configs/${theirs}_defconfig \
          config/u-boot/${ours}/config/default
  }

  do_diff amd64coreboot    coreboot64        x86_64
  do_diff i386coreboot     coreboot          x86
  do_diff gru_bob          chromebook_bob    default
  do_diff gru_kevin        chromebook_kevin  default
  do_diff qemu_arm64_12mb  qemu_arm64        default
