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.

+Subject: [PATCH 48/51] mb/dell: Convert E6400 into a variant
+
+All the GM45 Dell Latitudes should be nearly identical, so convert the
+E6400 port into a variant so that future ports for the other systems can
+share code with each other.
