[PATCH] libertas: split wlan_add_card()
Split wlan_add_card() into a part that just setups kernel parameters and
into the function libertas_activate_card(), which will implizitly use
hardware functions by the started thread.
This allows us later to do something like this:
priv = libertas_add_card();
priv->hw_command_to_host = if_usb_command_to_host;
priv->hw_xxxx = if_usb_xxxx;
priv->hw_yyyy = if_usb_yyyy;
wlan_activate_card()
and of course the CF driver can set it's own functions.
