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

+Subject: [PATCH 15/39] GM45-type CPUs: don't enable alternative SMRR
+
+This reverts the changes in coreboot revision:
+df7aecd92643d207feaf7fd840f8835097346644
+
+While this fix is *technically correct*, the one in
+coreboot, it breaks rebooting as tested on several
+GM45 ThinkPads e.g. X200, T400, when microcode
+updates are not applied.
+
+Since November 2022, Libreboot includes microcode
+updates by default, but it tells users how to remove
+it from the ROM (with cbfstool) if they wish.
+
+Well, with Libreboot 20221214, 20230319 and 20230413,
+mitigations present in Libreboot 20220710 (which did
+not have microcode updates) do not exist.
+
+This patch, along with the other patch to remove PECI
+support (which breaks speedstep when microcode updates
+are not applied) have now been re-added to Libreboot.
+
+It is still best to use microcode updates by default.
+These patches in coreboot are not critically urgent,
+and you can use the machines with or without them,
+regardless of ucode.
+
+I'll probably re-write this and the other patch at
+some point, applying the change conditionally upon
+whether or not microcode is applied.
+
+Pragmatism is a good thing. I recommend it.
