Tested on OptiPlex 3050 (via injecting grub2.elf into WIP coreboot
port).

see:
https://github.com/9elements/grub/commits/xhci-module-upstreaming-squash_v4/
grub only supports xhci on bios/uefi targets, but not coreboot.
some newer machines don't have ps/2 controllers, and boot in a
way where ehci isn't available at startup; the controller can't
be used by ehci code, there must be xhci support.
the code is from Patrick Rudolph working on behalf of 9elements.
the code was also sent here for review:
https://lists.gnu.org/archive/html/grub-devel/2020-12/msg00111.html
however, upstream never merged these patches. libreboot will have
to maintain these from now on. the patches have been rebased for
use with grub 2.12.

this replaces the previous behaviour, which erred
on a specific value of grub_errno, which was a
problem if other types of errors used that value.
due to the way i patch out the prefix error messages,
this new patch ensures that only those errors are
silenced. all other messages will be printed.

it still printed "error: ." on screen, instead
of the prefix message.
now it's silent. it just says:
Welcome to GRUB!

it can annoy some users, so just silence it. we don't need
a lot of modules so we only have a few, but some distro
grub configs can load modules frivilously.

still set grub_errno, and behave the same, but don't
print anything. just carry on execution as normal.

Faulty keyboards make GRUB unusable. Normally it happens
when a user plugs in a faulty USB keyboard, but if it's
the laptop keyboard, then GRUB becomes unusable and the
user cannot boot anything.
So, your laptop keyboard is a ticking timebomb if you use
GRUB; with this patch, that's no longer the case.

also, enable seabios_withgrub on e6400, but not grubfirst;
right now, we also support dgpu which would brick on
grubfirst. on my tested nvidia model, loading grub from
seabios worked, so i'm going to re-add seabios_grubfirst
functionality like in older libreboot revisions, enabled
selectively on a given target.
e6430 currently only has igpu support anyway, but i've done
the same thing there, in anticipation of future dgpu support.
e6400 and e6430 ec report scancode set 2 with translation
by default, but only actually output scancode set 1
grub is trying to use scancode set 2 without scancode
translation, so the key inputs get messed up
fix it by forcing scancode set 2 with translation, but
only on coreboot; other build targets on GRUB will
retain the same behaviour as before
courtesy goes to Nicholas Chin who inspired me, and
helped me to fix this. tested on Nicholas's E6400
and E6430, and my E6400; Riku also tested it on
non-Dell, as did I (some thinkpads), and all seems OK.
The new behaviour in coreboot GRUB is essentially no
different to that of SeaBIOS, which does the same.
