    mpc85xx: p1010: Fix Sophos RED 15w NAND partitions
    
    This partially reverts 78d259e7d28d212425164fc64bf0b9d8669d6020.
    That commit broke mounting the root fs on Sophos RED 15w due to
    partition size mismatch, and changed the partition sequence, causing
    the OpenWrt partition numbers to change from mtd3:kernel/mtd4:ubi to
    mtd4:kernel/mtd5:ubi.
    
    Fixes: 78d259e7d28d ("mpc85xx: fix some dtc warnings")
