    Kconfig: introduce writable boot device notion
    
    Indicate to the build system that a platform provides support
    for a writable boot device. The following will provide the
    necessary support:
    
    COMMON_CBFS_SPI_WRAPPER users
    soc/intel/apollolake
    soc/intel/baytrail
    soc/intel/braswell
    soc/intel/broadwell
    soc/intel/skylake
    
    The SPI_FLASH option is auto-selected if the platform provides
    write supoprt for the boot device and SPI flash is the boot
    device.
    
    Other platforms may provide similar support, but they do that
    in a device specific manner such as selecting SPI_FLASH
    explicitly. This provides clearance against build failures
    where chipsets don't provide SPI API implementations even
    though the platform may use a SPI flash to boot.
