coreboot/default: Update to 97bc693ab (2024-07-29)

Several patches are now merged upstream and no longer needed
in lbmk, such as the HP EliteBook 8560w patch, and related
patches. Some patches were changed, for example the Dell Latitude
ivb/snb laptops are now variants in coreboot, instead of being
individual ports; now they re-use the same base code.

This this, the corresponding files under config/submodules
have changed, for things like 3rdparty submodules e.g. libgfxinit,
and tarballs e.g. crossgcc.

This is long overdue, and will enable more boards to be added.
This newer revision will be used in the next release, and some
follow-up patches will merge these trees into default:

* coreboot/haswell
* coreboot/dell
