Run `./mk -l u-boot` to regenerate full configs from our new defconfigs.

Apply our preserved changes to the new U-Boot defconfigs. Upstream
rearranged memory layouts for Rockchip boards to a unified layout, which
got rid of CUSTOM_SYS_INIT_SP_ADDR and HAS_CUSTOM_SYS_INIT_SP_ADDR, and
will need a change to a related INIT_SP_RELATIVE later.

Normalize the positions of each line in the config by regenerating the
defconfig by `./mk -l u-boot` and then `./mk -s u-boot`, so that the
diff looks all green when we actually expand it to the full config.

Copy over the new upstream defconfigs from the refreshed U-Boot trees,
so we can fold our modifications into them. Manually done, but like:

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

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

    do_defconfig  amd64coreboot   coreboot64        x86_64
    do_defconfig  i386coreboot    coreboot          x86
    do_defconfig  gru_bob         chromebook_bob    default
    do_defconfig  gru_kevin       chromebook_kevin  default
    do_defconfig  qemu_arm_12mb   qemu_arm64        default

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

Run `./mk -s u-boot` to convert our configs into defconfigs, so we can
keep our changes to the old upstream defconfigs and re-apply them to the
new upstream defconfigs.

The bootflow menu is already the default boot command on x86. Switch
arm64 boards to that as well, so instead of booting the first thing we
find, we can easily choose what to boot.

U-Boot on ARM64 also enables the bootflow menu.

Set default U-Boot revision to v2024.10 and rebase patches on top of
that. The video subsystem now has switched to using the 'cyclic'
mechanism, so the code around one of the video patches changed a bit.

x86 boards were already switched to v2024.10. Update U-Boot for the
remaining ARM64 boards as usual:

- Turn old configs into defconfigs (./update trees -s u-boot)
- Save the diff from old upstream defconfig (diffconfig $theirs $ours)
- Update U-Boot revision, rebase patches, and clean old trees
- Prepare new U-Boot tree (./update trees -f u-boot)
- Review the diffconfigs to see if any options were renamed upstream
- Copy over the new upstream defconfigs and apply earlier diff
- Turn new defconfigs into configs (./update trees -l u-boot)

Set default U-Boot revision to v2024.07 and rebase patches on top of
that. One patch that fixes drawing box characters (UTF-8 to CP437) had
an alternative merged, another hack we have to fix regulator issues is
no longer neccessary as the issue is fixed, and my QEMU patches were
merged upstream, so drop these patches. One patch we have to disable
binman images can be replaced by a simpler alternative so drop it too.

Upstream kconfig status is still unstable, so updating configs with
`make oldconfig` would miss important upstream changes, since they rely
on carrying defaults via upstream defconfigs. Update the configs as
such, like before:

- Turn old configs into defconfigs (./update trees -s u-boot)
- Save the diff from old upstream defconfig (diffconfig $theirs $ours)
- Update U-Boot revision, rebase patches, and clean old trees
- Prepare new U-Boot tree (./update trees -f u-boot)
- Review the diffconfigs to see if any options were renamed upstream
- Copy over the new upstream defconfigs and apply earlier diff
- Turn new defconfigs into configs (./update trees -l u-boot)
