Furquan Shaikh 0dcc0662f3 util/cbfstool: Introduce concept of mmap_window 
This change adds the concept of mmap_window to describe how the SPI
flash address space is mapped to host address space on x86
platforms. It gets rid of the assumption that the SPI flash address
space is mapped only below the 4G boundary in host space. This is
required in follow up changes to be able to add more decode windows
for the SPI flash into the host address space.

Currently, a single mmap window is added i.e. the default x86 decode
window of maximum 16MiB size living just below the 4G boundary. If the
window is smaller than 16MiB, then it is mapped at the top of the host
window.

BUG=b:171534504
TEST=Verified using abuild with timeless option for all coreboot
boards that there is no change in the resultant coreboot.rom file.
