[TL-WA7210Nv2] GPIO support

[alexlist]

As of 20141123 (
512005f)

OpenWRT is running fine on the TL-WA7210Nv2, including networking support.

What is still missing is support for the GPIOs controlling the LEDs, handling the reset button, and e.g. switching between the different antennas and the external antenna port etc etc

https://forum.openwrt.org/viewtopic.php?id=46779 mentions that GPIO28 enables the LNA
