ramips: add support for unbranded XDX-RN502J board

This patch adds support for routers using a PCB marked XDX-RN502J
V2.0, such as some unbranded routers like this:

http://www.aliexpress.com/product-fm/516397994-Free-Shipping-300M-3G-WAN-Wireless-N-WiFi-USB-AP-Router-2-Antennas-wholesalers.html

some reports also state the Aceex 22Y uses the same board.

more information can be found in the following openwrt forum post
https://forum.openwrt.org/viewtopic.php?id=34878

[juhosg: fix checkpatch warnings, use the GENERIC_4M template]
