    drivers/spi: remove unconditional RW boot device initialization
    
    The SPI drivers for the various chipsets are not consistent in
    their handling of when they are accessible. Coupled with the
    unknown ordering of boot_device_init() being called this can
    lead to unexpected behavior (probing failures or hangs). Instead
    move the act of initializing the SPI flash boot device to when
    the various infrastructure requires its usage when it calls
    boot_device_rw(). Those platforms utilizing the RW boot device
    would need to ensure their SPI drivers are functional and
    ready when the call happens.
    
    This further removes any other systems failing to boot as
    reported in https://ticket.coreboot.org/issues/67.
