pc_wifi_drv: remove inactive disable 11n option

Browse Source 
The driver did not allow for setting module parameters and so far

users.

@ -96,10 +96,6 @@ Currently only WPA/WPA2 protection using a passphrase is supported and the the
SSID is copied verbatim. At the moment, there is no way to express or escape
non alphanumeric characters.
On certain cards, e.g. Intel Wireless 6200 ABG, it may be necessary to disable
the 11n mode. This can be achieved by setting the 'use_11n' attribute in
the 'wifi_config' node to 'no'.
The driver optionally reports the following information under the
label "devices" if requested in the config as depicted.
