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 Cc: Arnd Bergmann <arnd@arndb.de> Cc: Alan Cox <alan@lxorguk.ukuu.org.uk> Cc: Jiri Slaby <jslaby@suse.cz> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
