U-Boot has migrated to using upstream device-tree files for gru boards,
but the clock driver doesn't yet support setting rates for a certain
clock that upstream uses for the eDP display. It happens to work without
it, so for now remove the clock setting until the driver is fixed.

Commit 46e01c0e1dad ("u-boot: Avoid building U-Boot-only binman images")
added a patch that prevents an error while building U-Boot, due to some
U-Boot images needing a copy of BL31 that we are not passing in.

Removing build instructions for these images isn't really necessary,
when we can instead tell the build tool that it shouldn't exit with an
error. It checks a BINMAN_ALLOW_MISSING environment variable for this,
but just unconditionally replace the check with the argument.

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)

certain code checks for build.list, to skip it, for
example in items()

we already use config/data/grub to store grub config data
that applied to all trees

create these directories too:

config/data/coreboot
config/data/u-boot
config/data/seabios

move the respective build.list files in here, and also
to config/data/grub

now multi-tree projects contain, per directory, just the
target.cfg file and the patches directory. this is much
cleaner, because some of the logic can be simplified more

it doesn't build, at present, but isn't used by any
coreboot targets, so the build issue does not come up
during release builds, but i did find it laying around
during my audits.

x86 qemu is on todo for libreboot, on all x86 boards,
but the current config is broken, so: remove it.

it's very much a requirement that anything in lbmk should
work.

we don't need to do it in the release function

let them specific it, rather than falling back
to coreboot/default (can also be used for coreboot boards)

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

Signed-off-by: Leah Rowe <leah@libreboot.org>

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.
