Issue 229: Add driver/config for Wi2Wi WLAN module

Reported by Nikolaus Schaller, May 5, 2011

The module is connected to MMC2/SDIO in 4 bit mode.
This is the same as for the Overo Earth.

Therefore, this page should give a good start:

What we have to do:
* check hardware IF
* check SDIO driver
* check antenna
* power management (the Overo page reports that there is no power 
management)
* find out how to get/install the firmware
* check if we need the SDIO interrupt patch mentioned on the Overo 
page which limits the data rate

The driver is 'libertas' and needs to load a binary blob from 
Marvell. Debian comes with packages.
