Subject: ar71xx: add kernel support for the TL-WDR3500 board
WDR3500 is similar to WDR3600 except it doesn't have gigabit ethernet,
and has only 1 USB port.
Pending issues:
* Leds are not working at all (except power and wlan_5g)
* LAN switch ethernet ports are reversed with respect to case label.
[Label] -> soft device
[LAN1] -> eth0.4
[LAN2] -> eth0.3
[LAN3] -> eth0.2
[LAN4] -> eth0.1
Based on http://patchwork.openwrt.org/patch/3208/
