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.

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.
