cris: Remove obsolete ASYNC_SPLIT_TERMIOS behavior

ASYNC_SPLIT_TERMIOS behavior is a remnant of the long-dead /dev/cuaXX
callout device. Split termios handling was removed tree-wide in v2.5.71 by:

    [PATCH] tty_driver refcounting

    killed the last remnants of callout stuff - we don't need to mess with
    storing termios privately anymore.

which pre-dated the re-introduction into the cris serial driver
in v2.6.7 by:
