Leah Rowe 14b4838d49 coreboot/default: Re-base all patches
There were a lot of unnecessary patches, such as the VRAM
patches; as Nicholas Chin has explained to me, the drivers
for these machines will just allocate what RAM they want
anyway, so in a lot of cases the extra allocated Video RAM
simply reduces the total amount of memory for other uses.

In general, we have a lot of patches that have existed for
years. A much more aggressive sweep will be done in the next
major audit, especially when the revisions are updated again.

Leah Rowe 742c00331e coreboot/dell: move e6400 to new tree, dell
the ddr2 fix broke *ddr3* on gm45 thinkpads in
testing, depending on memory modules. this was
established by removing patches, re-doing
configs etc, on a user's X200 (testing gentoo
and freebsd). the X200 kept randomly rebooting
or having random glitches.

the configs themselves (gm45 thinkpads) will
also be re-done, because i found minor issues
unrelated, but this patch moves dell e6400 to
its own tree. the ddr2 fix is no longer present
in coreboot/default, only coreboot/dell.

i noticed minor differences in gm45 thinkpad
configs, when re-doing the configs, versus
what are currently in lbmk master; for instance,
vbt was not enabled anymore, on thinkpad x200.
modifications to these will be done separately.

Leah Rowe 34f5685337 fix raminit/coldboot on dell e6400
the patch included in this revision is pulled from:
https://review.coreboot.org/c/coreboot/+/54024/2

contrary to hell's assertion of "not for merge", this does
in fact work nicely on a dell e6400; nicholas chin tested
on e6400 and found that those RCOMP values are the same

nicholas was testing some errant modules that seemed to
fail raminit in coreboot. in some cases, dell e6400 would
regularly fail coldboot even though reboot was ok; this was
therefore the cause of suspicioun for it being raminit-related

with this patch from hell (Angel Pons, but knows as hell
on IRC) it should fix boot issue on Dell Latitude E6400
