    Add EM100 'hyper term' spi console support in ramstage & smm
    
    The EM100Pro allows the debug console to be sent over the SPI bus.
    This is not yet working in romstage due to the use of static variables
    in the SPI driver code.  It is also not working on chipsets that have
    SPI write buffers of less than 10 characters due to the 9 byte
    command/header length specified by the EM100 protocol.
    
    While this currently works only with the EM100, it seems like it would
    be useful on any logic analyzer with SPI debug - just filter on command
    bytes of 0x11.
