    mtd: nand: bf5xx_nand: remove unnecessary platform_set_drvdata()
    
    The driver core clears the driver data to NULL after device_release
    or on probe failure, since commit 0998d0631001288a5974afc0b2a5f568bcdecb4d
    (device-core: Ensure drvdata = NULL when no driver is bound).
    Thus, it is not needed to manually clear the device driver data to NULL.
