    [MTD] [NAND] Fix PCI ident table for CAFÉ NAND controller.
    
    It was only the very early prototypes which made the mistake of using
    the same device ident for all three functions on the device -- don't
    bother trying to express that in the PCI match table, since the tools
    don't cope. We can check in the probe routine instead, just in case.
    Also remember to terminate the table.
