    spi_flash: Differentiate between atomic/manual sequencing
    
    This adds a wrapper function and a Kconfig variable to differentiate
    between SPI controllers which use atomic cycle sequencing versus
    those where the transaction sequence is controlled manually. Currently
    this boils down to x86 vs. non-x86.
    
    Yes, it's hideous. The current API only worked because, for better or
    worse, x86 platforms have been homogeneous in this regard since they
    started using SPI as an alternative to FWH for boot flash. Now that
    we have non-x86 platforms which use general purpose SPI controllers,
    we should overhaul the entire SPI infrastructure to be more adaptable.
