    ar71xx: Added missing support for Linksys E2100L
    
    It's based on the WRT160NL according to
    https://wiki.openwrt.org/toh/linksys/e2100l
    
    Based on research done here: https://forum.openwrt.org/viewtopic.php?id=24244
    and here: https://forum.openwrt.org/viewtopic.php?pid=120791#p120791 this patch
    was conceived.
