Jeff Kirsher e8478de32e irda: Fix FSF address in file headers 
Several files refer to an old address for the Free Software Foundation
in the file header comment.  Resolve by replacing the address with
the URL <http://www.gnu.org/licenses/> so that we do not have to keep
updating the header comments anytime the address changes.

* Comment:
* jul/08/2002 : Rx buffer length should use Rx ring ptr.
* Oct/28/2002 : Add SB id for 3147 and 3177.
* jul/09/2002 : only implement two kind of dongle currently.
* Oct/02/2002 : work on VT8231 and VT8233 .
* Aug/06/2003 : change driver format to pci driver .
