    mtd: nand: denali: fix comment of denali_nand_info::flash_mem
    
    The same comment "Mapped io reg base address" for flash_reg and
    flash_mem probably due to the mistake of copy-paste work.
    Of course, the latter is not the register base address.
    
    Reword the comments using the terminology in the Denali User's Guide.
