    [MTD] [NOR] Fix Intel CFI driver for collie flash
    
    collie seems to contain LH28F640BF flash chips. According to
    http://sharp-world.com/products/device/flash/pdf/*FUM00701*@E.pdf
    (page 83) if they have 0x51 of Extended Query Table (number of hardware
    partitions) set to zero, they have a single fixed partition.
    This patch makes those chips work.
