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

-Subject: [PATCH 16/30] fix speedstep on x200/t400: Revert
- "cpu/intel/model_1067x: enable PECI"
-
-This reverts commit 70fea013c7ebd6d85a7806748233fcfd76802f5f.
-
-Enabling PECI without microcode updates loaded causes the CPUID feature set
-to become corrupted. And one consequence is broken SpeedStep. At least, that's
-my understanding looking at Intel Errata. This revert is not a fix, because
-upstream is correct (upstream assumes microcode updates). We will simply
-maintain this revert patch in Libreboot, from now on.
