Subject: [PATCH] kevin/custom.fmap: drop BIOS@0 region

On x86 platforms, it is necessary to wrap the entire image in a
BIOS@0 region which marks the memory-mapped flash image as needing
SMM protection.  Unfortunately this creates overlapping FMAP
regions, which flashrom cannot handle without a patch.

On arm64 platforms, the BIOS@0 region is not needed.  So let's not
include it.  This allows us to skip the flashrom patch on arm64.
