Staging: delete generic_serial drivers

Browse source 
No one has steped up to claim them, so as described in commit
4c37705877 (tty: move obsolete and broken
generic_serial drivers to drivers/staging/generic_serial/), they are now
deleted from the system.

config A2232
tristate "Commodore A2232 serial support (EXPERIMENTAL)"
depends on EXPERIMENTAL && ZORRO && BROKEN
---help---
This option supports the 2232 7-port serial card shipped with the
Amiga 2000 and other Zorro-bus machines, dating from 1989. At
a max of 19,200 bps, the ports are served by a 6551 ACIA UART chip
each, plus a 8520 CIA, and a master 6502 CPU and buffer as well. The
ports were connected with 8 pin DIN connectors on the card bracket,
for which 8 pin to DB25 adapters were supplied. The card also had
jumpers internally to toggle various pinning configurations.
This driver can be built as a module; but then "generic_serial"
will also be built as a module. This has to be loaded before
"ser_a2232". If you want to do this, answer M here.
config SX
tristate "Specialix SX (and SI) card support"
depends on SERIAL_NONSTANDARD && (PCI || EISA || ISA) && BROKEN
help
This is a driver for the SX and SI multiport serial cards.
Please read the file <file:Documentation/serial/sx.txt> for details.
This driver can only be built as a module ( = code which can be
inserted in and removed from the running kernel whenever you want).
The module will be called sx. If you want to do that, say M here.
config RIO
tristate "Specialix RIO system support"
depends on SERIAL_NONSTANDARD && BROKEN
help
This is a driver for the Specialix RIO, a smart serial card which
drives an outboard box that can support up to 128 ports. Product
information is at <http://www.perle.com/support/documentation.html#multiport>.
There are both ISA and PCI versions.
config RIO_OLDPCI
bool "Support really old RIO/PCI cards"
depends on RIO
help
Older RIO PCI cards need some initialization-time configuration to
determine the IRQ and some control addresses. If you have a RIO and
this doesn't seem to work, try setting this to Y.

These are a few tty/serial drivers that either do not build,
or work if they do build, or if they seem to work, are for obsolete
hardware, or are full of unfixable races and no one uses them anymore.
If no one steps up to adopt any of these drivers, they will be removed
in the 2.6.41 release.
