coreboot/next uprev: Fix T480 backlight keysHEADmaster

Backlight controls already worked on the T480/T480s, if you
used software-based controls e.g. set a hotkey for
xbacklight, but the actual Fn buttons on the keyboard did
not function at all; this patch fixes that issue

This also fixes LEDs on T480, on warm reboot, which are
otherwise off. It sets them back to the state they were
at on cold boot.

Both fixes are from Mate Kukri in the new T480 patchset.
In addition to these fixes, Mate made several code quality
improvements as part of efforts to upstream this code into
coreboot's main branch.

Updated coreboot T480 patchset to patchset 25. This change
will be reflected next in a modification to the Libreboot
documentation.

I had to make several other fixes on top of this; see diff.
A debug option was being enabled relating to stack overflow
detection, which we ought to avoid to mitigate over-zealous
build errors and stack corruption at boot; an errant option
for an EC we don't use was also being enabled, by some code
in coreboot relating to a Dasharo board; both issues have
been mitigated in this lbmk patch, by patching the upstream
coreboot build system in this patch.

As part of this change, the coreboot/next tree within lbmk
has been updated. Existing patches have been rebased.

This brings in the following changes from upstream, relative
to the previous revision used on coreboot/next:
