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

	  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.
