coreboot/default: bump revision to 2 August 2023

coreboot revision:
d86260a134575b083f35103e1cd5c7c7ad883bce
from 2 August 2023

The patches were updated. HP 8300 USDT has now been merged upstream,
so that patch is no longer included in lbmk.

SD card fix for E6400 merged upstream, so now it's removed in lbmk.
The nvidia E6400 patch (devicetree.cb) has not yet merged upstream.

The ifdtool --nuke option has been rebased.
Patches as follow-ups to earlier patches removed; for example, patches
that set VRAM to 352MB on GM45 have been removed, and replaced with
patches that just set 256MB in the first place (this is more stable).

This was mostly a clean rebase, of all the patches. It went smooth.
I haven't updated cros/haswell yet; the 4.11_branch revision used
on fam15h will also remain, for now.

The coreboot configurations have been updated, for this new
revision of coreboot.

+Subject: [PATCH 15/19] util/ifdtool: add --nuke flag (all 0xFF on region)
+
+When this option is used, the region's contents are overwritten
+with all ones (0xFF).
+
+Example:
+
+./ifdtool --nuke gbe coreboot.rom
+./ifdtool --nuke bios coreboot.com
+./ifdtool --nuke me coreboot.com
+
+Rebased since the last revision update in lbmk.
