tty: move obsolete and broken tty drivers to drivers/staging/tty/

As planned by Arnd Bergmann, this moves the following drivers to the
drivers/staging/tty/ directory where they will be removed after 2.6.41
if no one steps up to claim them.

-/*
- * linux/drivers/char/serial167.c
- *
- * Driver for MVME166/7 board serial ports, which are via a CD2401.
- * Based very much on cyclades.c.
- *
- * MVME166/7 work by Richard Hirst [richard@sleepie.demon.co.uk]
- *
- * ==============================================================
- *
- * static char rcsid[] =
- * "$Revision: 1.36.1.4 $$Date: 1995/03/29 06:14:14 $";
- *
- *  linux/kernel/cyclades.c
- *
- * Maintained by Marcio Saito (cyclades@netcom.com) and
- * Randolph Bentson (bentson@grieg.seaslug.org)
- *
- * Much of the design and some of the code came from serial.c
- * which was copyright (C) 1991, 1992  Linus Torvalds.  It was
- * extensively rewritten by Theodore Ts'o, 8/16/92 -- 9/14/92,
- * and then fixed as suggested by Michael K. Johnson 12/12/92.
- *
- * This version does not support shared irq's.
- *
- * $Log: cyclades.c,v $
- * Revision 1.36.1.4  1995/03/29  06:14:14  bentson
- * disambiguate between Cyclom-16Y and Cyclom-32Ye;
- *
- * Changes:
- *
- * 200 lines of changes record removed - RGH 11-10-95, starting work on
- * converting this to drive serial ports on mvme166 (cd2401).
- *
- * Arnaldo Carvalho de Melo <acme@conectiva.com.br> - 2000/08/25
- * - get rid of verify_area
- * - use get_user to access memory from userspace in set_threshold,
- *   set_default_threshold and set_timeout
- * - don't use the panic function in serial167_init
- * - do resource release on failure on serial167_init
- * - include missing restore_flags in mvme167_serial_console_setup
- *
- * Kars de Jong <jongk@linux-m68k.org> - 2004/09/06
- * - replace bottom half handler with task queue handler

-/* The serial driver boot-time initialization code!
-    Hardware I/O ports are mapped to character special devices on a
-    first found, first allocated manner.  That is, this code searches
-    for Cyclom cards in the system.  As each is found, it is probed
-    to discover how many chips (and thus how many ports) are present.
-    These ports are mapped to the tty ports 64 and upward in monotonic
-    fashion.  If an 8-port card is replaced with a 16-port card, the
-    port mapping on a following card will shift.
-
-    This approach is different from what is used in the other serial
-    device driver because the Cyclom is more properly a multiplexer,
-    not just an aggregation of serial ports on one card.
-
-    If there are more cards with more ports than have been statically
-    allocated above, a warning is printed and the extra ports are ignored.
