    nb/intel/x4x: Add DMI/EP init
    
    The values were obtained from vendor bios at runtime.
    I am not 100% sure of the sequence required to initiate them,
    but guessed from the gm45 code.  There may be some status bytes
    needed to be polled during the sequence that is missing,
    but as I don't have bios writer's datasheet it's very hard
    for me to know.
