isdn: remove isdn4linux
With all isdn4linux hardware drivers gone, this is only a wrapper around CAPI to support old user space. However, from looking at the mailing list, it seems that the last time anyone asked about it was in 2014, when the upgrade from a linux-2.4 installation failed, and mISDN was suggested as a replacement. The largest public ISDN network (Deutsche Telekom) was supposed to be shut down 2018, which must have drastically reduced the number of legacy installations. When we last discussed removing i4l in 2016, Karsten Keil suggested revisiting this in 2018. I guess this is overdue.

- This driver allows you to use an ISDN adapter for networking

- ISDN support in the linux kernel is moving towards a new API,
- called CAPI (Common ISDN Application Programming Interface).
- Therefore the old ISDN4Linux layer will eventually become obsolete.
- It is still available, though, for use with adapters that are not
- supported by the new CAPI subsystem yet.
