[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.

---help---
Driver for S514-PCI/ISA Synchronous Data Link Adapters (SDLA).
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.
config WANPIPE_CHDLC
bool "WANPIPE Cisco HDLC support"
depends on VENDOR_SANGOMA
---help---
Connect a WANPIPE card to a leased line using the Cisco HDLC.
- Supports Dual Port Cisco HDLC on the S514-PCI/S508-ISA cards
which allows user to build applications using the HDLC streaming API.
- CHDLC Streaming MULTILINK PPP that can bind multiple WANPIPE T1
cards into a single logical channel.
Say Y and the Cisco HDLC support, HDLC streaming API and
MULTILINK PPP will be included in the driver.
config WANPIPE_FR
bool "WANPIPE Frame Relay support"
depends on VENDOR_SANGOMA
help
Connect a WANPIPE card to a Frame Relay network, or use Frame Relay
API to develop custom applications.
Contains the Ethernet Bridging over Frame Relay feature, where
a WANPIPE frame relay link can be directly connected to the Linux
kernel bridge. The Frame Relay option is supported on S514-PCI
and S508-ISA cards.
Say Y and the Frame Relay support will be included in the driver.
config WANPIPE_X25
bool "WANPIPE X.25 support"
depends on VENDOR_SANGOMA
help
Connect a WANPIPE card to an X.25 network.
Includes the X.25 API support for custom applications over the
X.25 protocol. The X.25 option is supported on S514-PCI and
S508-ISA cards.
Say Y and the X.25 support will be included in the driver.
config WANPIPE_PPP
bool "WANPIPE PPP support"
depends on VENDOR_SANGOMA
help
Connect a WANPIPE card to a leased line using Point-to-Point
Protocol (PPP).
The PPP option is supported on S514-PCI/S508-ISA cards.
Say Y and the PPP support will be included in the driver.
config WANPIPE_MULTPPP
bool "WANPIPE Multi-Port PPP support"
depends on VENDOR_SANGOMA
help
Connect a WANPIPE card to a leased line using Point-to-Point
Protocol (PPP).
Uses in-kernel SyncPPP protocol over the Sangoma HDLC Streaming
adapter. In this case each Sangoma adapter port can support an
independent PPP connection. For example, a single Quad-Port PCI
adapter can support up to four independent PPP links. The PPP
option is supported on S514-PCI/S508-ISA cards.
Say Y and the Multi-Port PPP support will be included in the driver.

* To compile this code, one of the following constants must be defined:

* Platform Define
* -------- ------
* Linux _LINUX_
* SCO Unix _SCO_UNIX_
*
* 2. Supported adapter types:
*
* S502A
* ES502A (S502E)
* S503
* S507
* S508 (S509)
*
* 3. S502A Notes:
*
* There is no separate DPM window enable/disable control in S502A. It
* opens immediately after a window number it written to the HMCR
* register. To close the window, HMCR has to be written a value
* ????1111b (e.g. 0x0F or 0xFF).
*
* S502A DPM window cannot be located at offset E000 (e.g. 0xAE000).
*
* There should be a delay of ??? before reading back S502A status
* register.
*
* 4. S502E Notes:
*
* S502E has a h/w bug: although default IRQ line state is HIGH, enabling
* interrupts by setting bit 1 of the control register (BASE) to '1'
* causes it to go LOW! Therefore, disabling interrupts by setting that
* bit to '0' causes low-to-high transition on IRQ line (ghosty
* interrupt). The same occurs when disabling CPU by resetting bit 0 of
* CPU control register (BASE+3) - see the next note.
*
* S502E CPU and DPM control is limited:
*
* o CPU cannot be stopped independently. Resetting bit 0 of the CPUi
* control register (BASE+3) shuts the board down entirely, including
* DPM;
*
* o DPM access cannot be controlled dynamically. Ones CPU is started,
* bit 1 of the control register (BASE) is used to enable/disable IRQ,
* so that access to shared memory cannot be disabled while CPU is
* running.
