tty: move a number of tty drivers from drivers/char/ to drivers/tty/
As planned by Arnd Bergmann, this moves the following drivers from drivers/char/ to drivers/tty/ as that's where they really belong: amiserial nozomi synclink rocket cyclades moxa mxser isicom bfin_jtag_comm 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>
