staging: irda: remove remaining remants of irda code removal

There were some documentation locations that irda was mentioned, as well
as an old MAINTAINERS entry and the networking sysctl entries. Clean
these all out as this stuff really is finally gone.

 OSS sound drivers have their magic numbers constructed from the soundcard PCI
 ID - these are not listed here as well.
 
-IrDA subsystem also uses large number of own magic numbers, see
-``include/net/irda/irda.h`` for a complete list of them.
-
 HFS is another larger user of magic numbers - you can find them in
 ``fs/hfs/hfs.h``.
