    Fix memory size reporting on AMD family 14h systems for >= 4GB
    
    Applying Scott Duplichan's fix for memory >=4GB
    
    Adjusted it to the new directory structure (agesa_wrapper was renamed to
    just agesa).
    
    Boot-tested and confirmed to work, on my board Linux can now access the
    whole RAM.
