    drivers/spi: fix flash writes at page boundaries
    
    There was an assumption that all SPI controllers could
    consume a full page of data to write. However, that
    assumption doesn't hold when spi_crop_chunk() indicates
    sizes smaller than page size. If the requested offset isn't
    page aligned from the start then writes will fail corrupting
    data since a page boundary isn't honored.
    
    The spansion driver needed quite a bit more work to honor
    the spi_crop_chunk() result. It now mimics the other
    driver's code. Also, needed to add spi_crop_chunk() to
    marvell/bg4cd SoC to make google/cosmos build. SPI obviously
    doesn't work on that platform, but it fixes the build error.
