it causes s3 resume to break on t480s

more testing needed across the board(s)

a user reported that there is just a black screen at bootup
in 26.01 rc1 on these, but txtmode works.

only their x230 broke in corebootfb. their t430 and x200 they
tested worked fine.

txtmode works. this bug didn't affect 25.06, according to this
user.

no harm deleting these for now. i'll test it myself later (the
user isn't being very helpful with reporting) and fix whatever
the problem is.

coreboot updated the fsp file. we know the old one worked,
so no point testing the new one so close to a stable lbmk
release.

i've modified 3rdparty/fsp/ to re-add the old one as another
file, so that other boards are unaffected, and updated the
Kconfig so that the special file is used for x2e n150 only.

more specifically, added a second fsp submodule.

it's a bit dirty, but avoids bloating lbmk.git

see patches. coreboot making changes upstream. these
are used in the meantime.

this prevents build errors. (again, see patches, specifically
the 780 one explains rationale)

i got the variable wrong, putting the dollar sign inside
the brackets, rather than outside.

During routine build testing, I noticed that the VBT path was
wrong, because this port had been converted into a variant.

This is because of the OptiPlex 5040 port that is under
review on the coreboot Gerrit website.

lbmk uses make-oldconfig before running a build anyway,
so it would have been fine. however, it's best to just
enable it outright.

this change was generated by doing:

./mk -u coreboot t580_vfsp_16mb

which runs make-oldconfig on the configs.

Yes.

Thank you Johann C. Rode for this excellent coreboot port.

You're a star.
