    mtd: nand: denali: remove unused struct member denali_nand_info::idx
    
    The struct member "idx" was used as an index for debug_array long
    ago, but the DEBUG_DENALI feature was removed by commit 7cfffac06ca0
    ("nand/denali: use dev_xx debug function to replace nand_dbg_print
    and some printk").  Since then, this has been only initialized, but
    never referenced.
