    kirkwood: increase kernel partition of Linksyses
    
    At this moment kernel partition in Linksyses EA3500/E4200/EA4500 is
    ended before start of rootfs partition. It was introduced in 9808b9ae02
    and it broke easy revert to stock. Sysupgrade, when OFW is used, write
    whole stock image to kernel partition. Most likeley image will be bigger
    than small kernel partition and it make stock system invalid.
    
    This patch change size of kernel partitions and now it overlaps rootfs.
    Revert to stock will be possible again.
    
    Fixes: 9808b9ae02 ("kirkwood: switch to kernel 4.9")
