[WAN]: Remove broken and unmaintained Sangoma drivers.

The in-kernel Sangoma drivers are both not compiling and marked as BROKEN
since at least kernel 2.6.0.

Sangoma offers out-of-tree drivers, and David Mandelstam told me Sangoma
does no longer maintain the in-kernel drivers and prefers to provide them
as a separate installation package.

This patch therefore removes these drivers.

-	  WANPIPE from Sangoma Technologies Inc. <http://www.sangoma.com/>
-	  is a family of intelligent multiprotocol WAN adapters with data
-	  transfer rates up to 4Mbps. Cards support:
-
-	  - X.25, Frame Relay, PPP, Cisco HDLC protocols.
-
-	  - API for protocols like HDLC (LAPB), HDLC Streaming, X.25,
-	  Frame Relay and BiSync.
-
-	  - Ethernet Bridging over Frame Relay protocol.
-
-	  - MULTILINK PPP
-
-	  - Async PPP (Modem Dialup)
-
-	  The next questions will ask you about the protocols you want
-	  the driver to support.
-
-	  If you have one or more of these cards, say M to this option;
-	  and read <file:Documentation/networking/wan-router.txt>.
-
-	  To compile this driver as a module, choose M here: the
-	  module will be called wanpipe.
