arch/x86: Add option to disable default mmap_boot implementation

On certain platforms, the boot media is either not memory-mapped, or
    not mapped at the top of 4G. This makes the default mmap_boot
    implementation unsuitable. Add an option to allow such platforms to
    define their own mapping implementation.
