[gta02-core] Good news: also WLAN in bits

[Werner Almesberger]

Just got some good news from Sean: the WLAN daughterboards aren't
assembled yet. This means that we have more flexibility for placing
the components. With a little luck, there may even be space on the
side of the GSM module.

Now, the downside is that we need a few more symbols (the level
shifter, the WLAN module, and some smaller pieces). Any takers ?
