ISDN: eicon: Remove driver

I started looking at the history of this driver, and last time the
maintainer was active on the mailing list was when discussing how to
remove it. This was in 2012:

https://lore.kernel.org/lkml/4F4DE175.30002@melware.de/

It looks to me like this has in practice been an orphan for quite a while.
It's throwing warnings about stack size in a function that is in dire
need of refactoring, and it's probably a case of "it's time to call it".

-   For all systems, that are linked by Kernel Mode Linker this is ONLY one

-   IDI clients should look for IDI_DADAPTER, and use request function
-   of this adapter (sync request) in order to receive appropriate services:
-   - add new adapter
-   - remove existing adapter
-   - add adapter array notification
-   - remove adapter array notification
-   (read adapter is redundant in this case)
-   INPUT:
-   buffer - pointer to buffer that will receive adapter array
-   length  - length (in bytes) of space in buffer
-   OUTPUT:
-   Adapter array will be written to memory described by 'buffer'
-   If the last adapter seen in the returned adapter array is
-   IDI_DADAPTER or if last adapter in array does have type '0', then
-   it was enougth space in buffer to accommodate all available
-   adapter descriptors
-   *NOTE 1 (debug interface):
-   The IDI adapter of type 'IDI_DIMAINT' does register as 'request'
-   famous 'dprintf' function (of type DI_PRINTF, please look
-   include/debuglib.c and include/debuglib.h) for details.
-   So dprintf is not exported from module debug module directly,
-   instead of this IDI_DIMAINT is registered.
-   Module load order will receive in this case:
-   1. DIDD (this file)
-   2. DIMAINT does load and register 'IDI_DIMAINT', at this step
-   DIDD should be able to get 'dprintf', save it, and
-   register with DIDD by means of 'dprintf' function.
-   3. any other driver is loaded and is able to access adapter array
-   and debug interface
-   This approach does allow to load/unload debug interface on demand,
-   and save memory, it it is necessary.
