[PATCH] ramips: add support for Wavlink WL-WN576A2

Hi Thomas,

you are right, in the meantime I noticed that the reset button does not work.
I had overlooked the difference in the 5/6 of the name, but still, your image
made the device work nicely as an AP just like that. I'll look at the LEDs, too and
maybe submit a separate patch. Sorry for the confusion!

Cheers,
   Birger
