revert coreboot heap size patch

the patch:
https://review.coreboot.org/c/coreboot/+/78270

this has been reverted, because it caused s3 resume
issues on most intel laptops in libreboot.

i was going to merge this instead:
https://review.coreboot.org/c/coreboot/+/78623

however, it's under review, and this doesn't change
to the old behaviour; it keeps the new universal
config, but changes the default

we know the old logic works, so keep that for now.
in fact, the offending patch was only merged to
main in coreboot, one day before i recently
updated coreboot revs in coreboot/default - i used
a 12 october revision, the patch above is 11 october

i then ran "./update trees -u coreboot" which updated
the heap sizes back to the old defaults. this should
fix s3 suspend/resume where it was broken, in the
libreboot 20231021 release - a point release with this
and a few other fixes is planned soon.
