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 16/51] 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].
