Add the Embedded Wireless "Balin" platform, based on AR9344:
http://www.embeddedwireless.de/uploads/Balin_data_2016_10.pdf

The module comes already with the current vanilla OpenWRT firmware,
so no need to install "factory"-image, or any other stuff:-)

Can you please write the HW spec into the commit message ? the PDF link 
might be gone one day.
