staging: irda: remove the irda network stack and drivers

No one has publicly stepped up to maintain this broken codebase for
devices that no one uses anymore, so let's just drop the whole thing.

If someone really wants/needs it, we can revert this and they can fix
the code up to work properly.

To use the IrDA protocols within Linux you will need to get a suitable copy
of the IrDA Utilities. More detailed information about these and associated
programs can be found on http://irda.sourceforge.net/
For more information about how to use the IrDA protocol stack, see the
Linux Infrared HOWTO by Werner Heuser <wehe@tuxmobil.org>:
<http://www.tuxmobil.org/Infrared-HOWTO/Infrared-HOWTO.html>
There is an active mailing list for discussing Linux-IrDA matters called
irda-users@lists.sourceforge.net

The irda code will be removed soon from the kernel tree as it is old and
obsolete and broken.
Don't worry about fixing up anything here, it's not needed.

config IRCOMM
tristate "IrCOMM protocol"
depends on IRDA && TTY
help
Say Y here if you want to build support for the IrCOMM protocol.
To compile it as modules, choose M here: the modules will be
called ircomm and ircomm_tty.
IrCOMM implements serial port emulation, and makes it possible to
use all existing applications that understands TTY's with an
infrared link. Thus you should be able to use application like PPP,
minicom and others.
