[RFC] Fix Free Software Foundation address in file headers

This came up when John Fastabend got a patch to fix up the headers in
the drivers/scsi/ directory and so I did a quick search of the network
drivers and found several instances in the file headers where an old FSF
address remains.  The old address is:

59 Temple Place - Suite 330
Boston, MA 02111-1307

The current address is:

51 Franklin Street - Fifth Floor
Boston, MA 02110-1301

I am wondering whether it may be best to just put a link to the Free
Software Foundation web page instead of having to update the address any
time a change is made.

Either way, I feel the address either needs to get corrected or changed
to the URL, even though I am not a fan of huge patch series to make
trivial changes like this.

Thoughts?

Cheers,
Jeff Kirsher
