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

-** 
-** How to use this file:
-** 
-** To send a command down a rup, you need to allocate a command block, fill
-** in the packet information, fill in the command number, fill in the pre-
-** and post- functions and arguments, and then add the command block to the
-** queue of command blocks for the port in question. When the port is idle,
-** then the pre-function will be called. If this returns RIO_FAIL then the
-** command will be re-queued and tried again at a later date (probably in one
-** clock tick). If the pre-function returns NOT RIO_FAIL, then the command
-** packet will be queued on the RUP, and the txcontrol field set to the
-** command number. When the txcontrol field has changed from being the
-** command number, then the post-function will be called, with the argument
-** specified earlier, a pointer to the command block, and the value of
-** txcontrol.
-** 
-** To allocate a command block, call RIOGetCmdBlk(). This returns a pointer
-** to the command block structure allocated, or NULL if there aren't any.
-** The block will have been zeroed for you.
-** 
-** The structure has the following fields:
-** 
-** struct CmdBlk
-** {
-**	 struct CmdBlk *NextP;		  ** Pointer to next command block   **
-**	 struct PKT	 Packet;		** A packet, to copy to the rup	**
-**			int	 (*PreFuncP)();  ** The func to call to check if OK **
-**			int	 PreArg;		** The arg for the func			**
-**			int	 (*PostFuncP)(); ** The func to call when completed **
-**			int	 PostArg;	   ** The arg for the func			**
-** };
-** 
-** You need to fill in ALL fields EXCEPT NextP, which is used to link the
-** blocks together either on the free list or on the Rup list.
-** 
-** Packet is an actual packet structure to be filled in with the packet
-** information associated with the command. You need to fill in everything,
-** as the command processor doesn't process the command packet in any way.
-** 
-** The PreFuncP is called before the packet is enqueued on the host rup.
-** PreFuncP is called as (*PreFuncP)(PreArg, CmdBlkP);. PreFuncP must
-** return !RIO_FAIL to have the packet queued on the rup, and RIO_FAIL
-** if the packet is NOT to be queued.
-** 
-** The PostFuncP is called when the command has completed. It is called
-** as (*PostFuncP)(PostArg, CmdBlkP, txcontrol);. PostFuncP is not expected
-** to return a value. PostFuncP does NOT need to free the command block,
-** as this happens automatically after PostFuncP returns.
-** 
-** Once the command block has been filled in, it is attached to the correct
-** queue by calling RIOQueueCmdBlk( HostP, Rup, CmdBlkP ) where HostP is
-** a pointer to the struct Host, Rup is the NUMBER of the rup (NOT a pointer
-** to it!), and CmdBlkP is the pointer to the command block allocated using
-** RIOGetCmdBlk().
