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. 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.

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