coreboot/dell: merge into coreboot/default
The libgfxinit patch and other patches e.g. DDR2 fix, are now provided in coreboot/default. The Latitude E6400 is now using the newer coreboot revision from late July 2024. Some other configs had to change because of this, relating to the new way that Nicholas handles timing on LVDS displays with the E6400 port; a default 96MHz clock is still used for pixel reference clock, overridden with a value of 100MHz on other GM45 machines, where 96MHz was previously hardcoded.

-Subject: [PATCH 1/9] 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.
