    x86: Set BOOT_MEDIA_SPI_BUS
    
    BOOT_MEDIA_SPI_BUS is a Kconfig variable used on some ARM-based
    platforms to set up CBFS media. It turns out it can also be helpful
    for setting up the eventlog which is intended to reside on the same
    SPI flash as CBFS. Setting it for x86 will allow us to remove an
    assumption about which SPI bus is used for this flash device.
    
    Long term this can go away as we come up with a better abstraction
    for the eventlog's backing store. This is only intended to help us
    get from here to there.
