Some of the ISDN stack was deleted in the 5.3 window as per Paul's cleanup
patch. The vast majority of the remainder was moved to staging so let's
disable it in Fedora as it's unlikely to be used, and if se we can feed this
back to upstream.
For reference the main details from upstream are in these commits:
8a7e8ff8ce8a : ISDN removal/move merge overview
6d97985072dc : isdn: move capi drivers to staging
9c3c0c204814 : isdn: remove isdn4linux
85993b8c9786 : isdn: remove hisax driver
It was suggested that base-debug and base-generic were not good names
to use. Further discussion led to using configs/fedora for the base
config files and configs/rhel for any overrides.
This patch does a plain
mkdir configs/fedora
git mv configs/base-{generic,debug} configs/fedora
No code changes.
