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 22/65] mb/dell: Add Latitude E5520 (Sandy Bridge)
-
-Mainboard is Krug 15". I do not physically have this system; someone
-with physical access to one sent me the output of autoport which I then
-modified to produce this port. I was also sent the VBT binary, which was
-obtained from `/sys/kernel/debug/dri/0/i915_vbt` while running version
-A14 of the vendor firmware.
-
-This was originally tested and found to be working as a standalone
-board port in Libreboot, but this variant based port in upstream
-coreboot has not been tested.
-
-This can be internally flashed by sending a command to the EC, which
-causes the EC to pull the FDO pin low and the firmware to skip setting
-up any chipset based write protections [1]. The EC is the SMSC MEC5055,
-which seems to be compatible with the existing MEC5035 code.
