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

As planned by Arnd Bergmann, this moves the following drivers to the
drivers/staging/generic_serial directory where they will be removed
after 2.6.41 if no one steps up to claim them.
	generic_serial
	rio
	ser_a2232
	sx
	vme_scc

- * Revision history:
- * Revision 1.33  2000/03/09 10:00:00  pvdl,wolff
- * - Fixed module and port counting
- * - Fixed signal handling
- * - Fixed an Ooops
- * 
- * Revision 1.32  2000/03/07 09:00:00  wolff,pvdl
- * - Fixed some sx_dprintk typos
- * - added detection for an invalid board/module configuration
- *
- * Revision 1.31  2000/03/06 12:00:00  wolff,pvdl
- * - Added support for EISA
- *
- * Revision 1.30  2000/01/21 17:43:06  wolff
- * - Added support for SX+
- *
- * Revision 1.26  1999/08/05 15:22:14  wolff
- * - Port to 2.3.x
- * - Reformatted to Linus' liking.
- *
- * Revision 1.25  1999/07/30 14:24:08  wolff
- * Had accidentally left "gs_debug" set to "-1" instead of "off" (=0).
- *
- * Revision 1.24  1999/07/28 09:41:52  wolff
- * - I noticed the remark about use-count straying in sx.txt. I checked
- *   sx_open, and found a few places where that could happen. I hope it's
- *   fixed now.
- *
- * Revision 1.23  1999/07/28 08:56:06  wolff
- * - Fixed crash when sx_firmware run twice.
- * - Added sx_slowpoll as a module parameter (I guess nobody really wanted
- *   to change it from the default... )
- * - Fixed a stupid editing problem I introduced in 1.22.
- * - Fixed dropping characters on a termios change.
- *
- * Revision 1.22  1999/07/26 21:01:43  wolff
- * Russell Brown noticed that I had overlooked 4 out of six modem control
- * signals in sx_getsignals. Ooops.
- *
- * Revision 1.21  1999/07/23 09:11:33  wolff
- * I forgot to free dynamically allocated memory when the driver is unloaded.
- *
- * Revision 1.20  1999/07/20 06:25:26  wolff
- * The "closing wait" wasn't honoured. Thanks to James Griffiths for
- * reporting this.
- *
- * Revision 1.19  1999/07/11 08:59:59  wolff
- * Fixed an oops in close, when an open was pending. Changed the memtest
- * a bit. Should also test the board in word-mode, however my card fails the
- * memtest then. I still have to figure out what is wrong...
- *
- * Revision 1.18  1999/06/10 09:38:42  wolff
- * Changed the format of the firmware revision from %04x to %x.%02x .
- *
- * Revision 1.17  1999/06/04 09:44:35  wolff
- * fixed problem: reference to pci stuff when config_pci was off...
- * Thanks to Jorge Novo for noticing this.
- *
- * Revision 1.16  1999/06/02 08:30:15  wolff
- * added/removed the workaround for the DCD bug in the Firmware.
- * A bit more debugging code to locate that...
- *
- * Revision 1.15  1999/06/01 11:35:30  wolff
- * when DCD is left low (floating?), on TA's the firmware first tells us
- * that DCD is high, but after a short while suddenly comes to the
- * conclusion that it is low. All this would be fine, if it weren't that
- * Unix requires us to send a "hangup" signal in that case. This usually
- * all happens BEFORE the program has had a chance to ioctl the device
- * into clocal mode..
- *
- * Revision 1.14  1999/05/25 11:18:59  wolff
- * Added PCI-fix.
- * Added checks for return code of sx_sendcommand.
- * Don't issue "reconfig" if port isn't open yet. (bit us on TA modules...)
- *
- * Revision 1.13  1999/04/29 15:18:01  wolff
- * Fixed an "oops" that showed on SuSE 6.0 systems.
- * Activate DTR again after stty 0.
- *
- * Revision 1.12  1999/04/29 07:49:52  wolff
- * Improved "stty 0" handling a bit. (used to change baud to 9600 assuming
- *     the connection would be dropped anyway. That is not always the case,
- *     and confuses people).
- * Told the card to always monitor the modem signals.
- * Added support for dynamic  gs_debug adjustments.
- * Now tells the rest of the system the number of ports.
- *
- * Revision 1.11  1999/04/24 11:11:30  wolff
- * Fixed two stupid typos in the memory test.
- *
- * Revision 1.10  1999/04/24 10:53:39  wolff
- * Added some of Christian's suggestions.
- * Fixed an HW_COOK_IN bug (ISIG was not in I_OTHER. We used to trust the
- * card to send the signal to the process.....)
- *
- * Revision 1.9  1999/04/23 07:26:38  wolff
- * Included Christian Lademann's 2.0 compile-warning fixes and interrupt
- *    assignment redesign.
- * Cleanup of some other stuff.
- *
- * Revision 1.8  1999/04/16 13:05:30  wolff
- * fixed a DCD change unnoticed bug.
- *
- * Revision 1.7  1999/04/14 22:19:51  wolff
- * Fixed typo that showed up in 2.0.x builds (get_user instead of Get_user!)
- *
- * Revision 1.6  1999/04/13 18:40:20  wolff
- * changed misc-minor to 161, as assigned by HPA.
- *
- * Revision 1.5  1999/04/13 15:12:25  wolff
- * Fixed use-count leak when "hangup" occurred.
- * Added workaround for a stupid-PCIBIOS bug.
- *
- *
- * Revision 1.4  1999/04/01 22:47:40  wolff
- * Fixed < 1M linux-2.0 problem.
- * (vremap isn't compatible with ioremap in that case)
- *
- * Revision 1.3  1999/03/31 13:45:45  wolff
- * Firmware loading is now done through a separate IOCTL.
- *
- * Revision 1.2  1999/03/28 12:22:29  wolff
- * rcs cleanup
- *
- * Revision 1.1  1999/03/28 12:10:34  wolff
- * Readying for release on 2.0.x (sorry David, 1.01 becomes 1.1 for RCS). 
- *
- * Revision 0.12  1999/03/28 09:20:10  wolff
- * Fixed problem in 0.11, continueing cleanup.
- *
- * Revision 0.11  1999/03/28 08:46:44  wolff
- * cleanup. Not good.
- *
- * Revision 0.10  1999/03/28 08:09:43  wolff
- * Fixed loosing characters on close.
- *
- * Revision 0.9  1999/03/21 22:52:01  wolff
- * Ported back to 2.2.... (minor things)
- *
- * Revision 0.8  1999/03/21 22:40:33  wolff
- * Port to 2.0
- *
- * Revision 0.7  1999/03/21 19:06:34  wolff
- * Fixed hangup processing.
- *
- * Revision 0.6  1999/02/05 08:45:14  wolff
- * fixed real_raw problems. Inclusion into kernel imminent.
- *
- * Revision 0.5  1998/12/21 23:51:06  wolff
- * Snatched a nasty bug: sx_transmit_chars was getting re-entered, and it
- * shouldn't have. THATs why I want to have transmit interrupts even when
- * the buffer is empty.
- *
- * Revision 0.4  1998/12/17 09:34:46  wolff
- * PPP works. ioctl works. Basically works!
- *
- * Revision 0.3  1998/12/15 13:05:18  wolff
- * It works! Wow! Gotta start implementing IOCTL and stuff....
- *
- * Revision 0.2  1998/12/01 08:33:53  wolff
- * moved over to 2.1.130
- *
- * Revision 0.1  1998/11/03 21:23:51  wolff
- * Initial revision. Detects SX card.
