    mtd: denali: detect the number of banks before resetting NAND
    
    Commit c89eeda810f0ec4f0eee0206ebb79e476df9f83e (mtd: denali: detect the
    number of banks) introduced runtime detection of the number of banks.
    
    However, denali_nand_reset() uses uses denanli_nand_info::max_banks so
    we need to detect the maximum number of banks before doing the reset.
