    bcm4908: pad firmware image bootfs JFFS2 partition to 8 MiB
    
    This way MTD "bootfs" partition will be always 8+ MiB. This should be
    enough for any custom / future firmware to fit its bootfs (e.g. big
    kernel) without having to repertition whole flash. That way we can
    preserve UBI and its erase counters during sysupgrade.
