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 34/65] nb/intel/haswell: make IOMMU a runtime option
-
-When I tested graphics cards on a coreboot port for Dell
-OptiPlex 9020 SFF, I could not use a graphics card unless
-I set iommu=off on the Linux cmdline.
-
-Coreboot's current behaviour is to check whether the CPU
-has vt-d support and, if it does, initialise the IOMMU.
-
-This patch maintains the current behaviour by default, but
-allows the user to turn *off* the IOMMU, even if vt-d is
-supported by the host CPU.
-
-If iommu=Disable is specified, the check will not be
-performed, and the IOMMU will be left disabled. This option
-has been added to all current Haswell boards, though it is
-recommended to leave the IOMMU turned on in most setups.
