configs: imx6ulpico: Add Wifi support

Browse Source 
imx6ulpico has a BCM4339 Wifi chip. Add Wifi support by default
to allow a better customer experience.

The dts patch has already been sent to the linux-arm-kernel list
and we can remove it once it reaches a mainline kernel (in
version 4.9 probably).
