    haswell: implement ramstage caching in SMM region
    
    Cache the relocated ramstage into the SMM region. There is
    a reserved region within the final SMM region (TSEG). Use that
    space to cache the relocated ramstage program. That way, on S3 resume
    there is a copy that can be loaded quickly instead of accessing the
    flash. Caching the ramstage in the SMM space is also helpful in that
    it prevents the OS from tampering with the ramstage program.
