This makes the EM100 option visible in Kconfig that makes sure that the
SPI settings that coreboot applies are valid for the EM100 that has some
limitations on the maximum SPI frequency and possibly on the supported
SPI modes. For the PSP SPI settings, the mainboard still might need to
provide EM100-specific settings for EFS_SPI_READ_MODE, EFS_SPI_SPEED and
EFS_SPI_MICRON_FLAG. Haven't checked if those PSP settings are correctly
integrated for Cezanne.
