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 26/65] mb/dell: Add Latitude E6330 (Ivy Bridge)
-
-Mainboard is QAL70/LA-7741P. 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 A21 of the vendor firmware. This port has not been tested.
-
-The EC is the SMSC MEC5055, which seems to be compatible with the
-existing MEC5035 code. As with the other Dell systems with this EC, this
-board is assumed to be internally flashable using an EC command that
-tells it to pull the FDO pin low on the next boot, which also tells the
-vendor firmware to disable all write protections to the flash [1].
