    mtd: lpc32xx: drop bitflip_threshold initialization
    
    These drivers don't need to explicitly initialize their bitflip
    thresholds. The comment is no longer correct, since nand_scan_tail()
    performs this initialization as of the following commit:

            mtd: nand: initialize bitflip_threshold prior to BBT scanning
    
    (It seems there were some parallel efforts on writing/submitting these
    drivers, and Shmulik's bug fix.)
