gigaset: allow building without I4L

Add a dummy LL interface to the Gigaset driver so that it can be
built and, in a limited way, used without the ISDN4Linux subsystem.

Impact: new configuration alternative

If you have one of these devices, say M here and for at least
one of the connection specific parts that follow.
This will build a module called "gigaset".
Note: If you build the ISDN4Linux subsystem (ISDN_I4L)
as a module, you have to build this driver as a module too,
otherwise the Gigaset device won't show up as an ISDN device.
