net: remove sb1000 cable modem driver

This one is hilariously outdated, it provided a faster downlink over
TV cable for users of analog modems in the 1990s, through an ISA card.

The web page for the userspace tools has been broken for 25 years, and
the driver has only ever seen mechanical updates.

-	  This is a driver for the General Instrument (also known as
-	  NextLevel) SURFboard 1000 internal
-	  cable modem. This is an ISA card which is used by a number of cable
-	  TV companies to provide cable modem access. It's a one-way
-	  downstream-only cable modem, meaning that your upstream net link is
-	  provided by your regular phone modem.
-
-	  At present this driver only compiles as a module, so say M here if
-	  you have this card. The module will be called sb1000. Then read
-	  <file:Documentation/networking/device_drivers/cable/sb1000.rst> for
-	  information on how to use this module, as it needs special ppp
-	  scripts for establishing a connection. Further documentation
-	  and the necessary scripts can be found at:
-
-	  <http://www.jacksonville.net/~fventuri/>
-	  <http://home.adelphia.net/~siglercm/sb1000.html>

-
-	  If you don't have this card, of course say N.
