[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.
