Wifi support added for WP76xx

Hello,

legato 17.09.0 supports Wifi for WP76xx.
Which Wifi is meant? Wifi built-In on Mango-Red or IoT Card Wifi?

Hi,
I think it is IoT expension card.
You can see here:

Hi,
It should support both. Legato is based on interfaces. So If you use Mango-Red, WiFi interfaces should be implemented and ready to use. If you use Mango-Green with IoT WiFi card, the same interfaces should be implemented. In other words the same code should work on Mango-Red without IoT WiFi card and on Mango-Green with IoT WiFi card.
