isdn: gigaset: remove i4l support

isdn4linux is getting removed, and the gigaset driver can still use the CAPI support, so this can all go away. Signed-off-by: Arnd Bergmann <[email protected]>

 2.3. CAPI
      ----
-     If the driver is compiled with CAPI support (kernel configuration option
-     GIGASET_CAPI) the devices will show up as CAPI controllers as soon as the
-     corresponding driver module is loaded, and can then be used with CAPI 2.0
-     kernel and user space applications. For user space access, the module
-     capi.ko must be loaded.
-
-     Legacy ISDN4Linux applications are supported via the capidrv
-     compatibility driver. The kernel module capidrv.ko must be loaded
-     explicitly with the command
-        modprobe capidrv
-     if needed, and cannot be unloaded again without unloading the driver
-     first. (These are limitations of capidrv.)

      Most distributions handle loading and unloading of the various CAPI
      modules automatically via the command capiinit(1) from the capi4k-utils
      package or a similar mechanism. Note that capiinit(1) cannot unload the
      Gigaset drivers because it doesn't support more than one module per
      driver.
 
-2.4. ISDN4Linux
-     ----------
-     If the driver is compiled without CAPI support (native ISDN4Linux
-     variant), it registers the device with the legacy ISDN4Linux subsystem
-     after loading the module. It can then be used with ISDN4Linux
-     applications only. Most distributions provide some configuration utility
-     for setting up that subsystem. Otherwise you can use some HOWTOs like
