it's only needed for each board

arch no longer needs to be set, on multi-tree projects,
and it has been renamed to xarch
the new behaviour is: if xarch is set, treat it as a
list of crossgcc targets and go through the list. set
the first one as the target, for what lbmk builds, but
build all of the defined crossgccc targets
crossgcc_ada is now xlang, and defines which languages
to build, rather than whether to build gcc-gnat

only call crossgcc for coreboot and u-boot, but use
hostcc for everything else. simplify the checking of
which architecture to compile for. "arch" in target.cfg
files has been modified, to allow further simplification.
without this patch, the logic currently only *barely* avoids
using crossgcc on things like utils, and only works in practise
because, in practise, lbmk only works on x86_64 anyway.
the new logic, as per this patch, is simpler and more robust.

Add a U-Boot build for the qemu_x86_12mb board. The config is a copy of
the upstream "coreboot" defconfig, but with OF_EMBED=y.

Add my upstream U-Boot series enabling video console support by default
for QEMU ARM virtual machines. Similarly, enable the related config
options for our builds using savedefconfig and olddefconfig.
The resulting ROM can be booted with a command line like:
qemu-system-aarch64 \
-machine virt,secure=on,virtualization=on \
-cpu cortex-a72 -m 1G \
-serial stdio -device VGA \
-device qemu-xhci \
-device usb-kbd -device usb-mouse \
-bios bin/qemu_arm64_12mb/*.rom

By default U-Boot stores EFI variables in a ubootefi.var file in
whatever EFI System Partition it finds, which would be a FAT filesystem.
I'm occasionally finding out while testing that my ESPs somehow end up
with a corrupted filesystem, and I'm suspecting it's this.
For now, disable storing EFI environment variables on disk so that
U-Boot doesn't try to manipulate the filesystem.

Enable U-Boot commands to manipulate EFI environment storage, to
self-test EFI implementation, and to run a basic EFI test application.
These are so that we can test and debug EFI functionality easier.

U-Boot upstream is switching to a new code framework for discovering and
booting OSes ("Standard Boot", or "bootstd"). Enable more features for
it, including commands we can use for introspection and debugging.

Normally U-Boot immediately resets the board on a panic. I had run into
"Synchronous Abort"s from shim and rEFInd, and having a traceback in
those cases can be useful. Hang instead of resetting, so the panic
reason stays on the screen.

We should be able to power the board off from U-Boot command line.
Enable the "poweroff" command for gru boards so we can.

U-Boot can keep a "copy" framebuffer to read from, for devices where
reading from hardware framebuffer is expensive. This needs the video
driver to support it. The Rockchip video driver doesn't need or support
it, so this option does nothing on gru boards. Disable it.

U-Boot upstream used to have 16KB for EFI variables, and this was
causing problems with shim. Commit f0236acbc663 ("u-boot: Increase EFI
variable buffer size") fixed this by raising it to 32KB in our builds.
It has now been raised to 64K upstream, so raise it here as well.

For Rockchip boards U-Boot tries to build SPI and MMC images that
require an externally built BL31 file to be provided, and the build
fails otherwise. This is not really as configurable as it should be.
In Libreboot, we only care about the build outputs for U-Boot proper.
There is a BL31 built during our coreboot builds, but using that in
U-Boot builds is a chicken-and-egg problem. Building BL31 outside the
coreboot build and passing it to both projects is possible, but needs
work.
For now, stop trying to build these U-Boot-only images as a workaround,
by removing the binman image descriptions from the device-tree sources.
Additionally, disable in our configs the BINMAN_FDT functionality that
allows using these at runtime as it requires them to be present.

U-Boot upstream has added a reference counting for regulator enable
actions which somehow makes gru-kevin unbootable. Add a workaround
that makes it work again.

Set default U-Boot revision to v2023.01 and rebase patches on top of
that. Another series about 16x32 fonts was merged upstream, so drop some
now-unnecessary patches we had for that. For the video damage tracking
series, switch to the version I'm trying to upstream.
Upstream kconfig status is a bit 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:
- Turn old configs into defconfigs (./update project 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 project 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 project trees -l u-boot)

The U-Boot build for qemu_arm64_12mb board refers to a code revision
whereas it uses the common "default" tree, remove the bad reference.

The "u-boot.bin" file generated by U-Boot builds is a raw binary. When
adding payloads to a CBFS, we need to use ELF files with add-payload
or manually pass the entry point and load address of the payload binary
with add-flat-binary.
We primarily use the "u-boot.elf" which gets build with the REMAKE_ELF
option, as it also has the necessary device-tree binary that U-Boot
usually needs to work. When the option is not set (e.g. for QEMU), we
need to use the "u-boot" file which is an ELF.
