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.
