CC: 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.
