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] mb/dell/e6400: Use 100 MHz reference clock for display
-
-The E6400 uses a 100 MHz reference clock for spread spectrum support on
-LVDS, whereas libgfxinit previously assumed a 96 MHz input clock. For
-the more common 1280 x 800 display panels, the numerical error was not
-large enough to cause noticable issues, but the actual pixel clock
-frequency derived from a 100 MHz reference using PLL configs calculated
-assuming a 96 MHz reference was not close enough for 1440 x 900 panels,
-which require a much higher pixel clock. This resulted in a garbled
-display in the pre-OS graphics environment provided by libgfxinit.
