isdn: fix a few Kconfig imperfections

1. Rewrite the outdated help texts for config options ISDN and ISDN_CAPI.
2. The MISDN config option appeared between ISDN_I4L and the I4L hardware
   driver options; move it to a less irritating place.
3. HYSDN is not in fact an I4L driver, and needn't depend on ISDN_I4L, so
   move it from the I4L section to the general section.
4. ISDN_HDLC is now also used by drivers outside I4L.  Move it from the
   I4L section to the general section, too.

-         ISDN ("Integrated Services Digital Networks", called RNIS in France)
-         is a special type of fully digital telephone service; it's mostly
-         used to connect to your Internet service provider (with SLIP or
-         PPP).  The main advantage is that the speed is higher than ordinary
-         modem/telephone connections, and that you can have voice
-         conversations while downloading stuff.  It only works if your
-         computer is equipped with an ISDN card and both you and your service
-         provider purchased an ISDN line from the phone company.  For
-         details, read <http://www.alumni.caltech.edu/~dank/isdn/> on the WWW.
+         ISDN ("Integrated Services Digital Network", called RNIS in France)
+         is a fully digital telephone service that can be used for voice and
+         data connections.  If your computer is equipped with an ISDN
+         adapter you can use it to connect to your Internet service provider
+         (with SLIP or PPP) faster than via a conventional telephone modem
+         (though still much slower than with DSL) or to make and accept
+         voice calls (eg. turning your PC into a software answering machine
+         or PABX).
 
          Select this option if you want your kernel to support ISDN.
