iwmc3200top: Add Intel Wireless MultiCom 3200 top driver.

This patch adds Intel Wireless MultiCom 3200 top driver.
IWMC3200 is 4Wireless Com CHIP (GPS/BT/WiFi/WiMAX).
Top driver is responsible for device initialization and firmware download.
Firmware handled by top is responsible for top itself and
as well as bluetooth and GPS coms. (Wifi and WiMax provide their own firmware)
In addition top driver is used to retrieve firmware logs
and supports other debugging features
