[RFC 1/13] Char: nozomi, remove unneded stuff

[Jiri Slaby <jirislaby@gmail.com>]

Frank, could you comment (and test) following changes to the nozomi driver?
I did them before you post the updated version and rediffed them a while
ago, I hope I haven't done any mistake while doing it.

Thanks.

nozomi, remove unneded stuff

- tty_termios* are set to tty struct, but tty_register_driver overwrites it
  with its own values (or NULLs), no need to have these pointers stored
- [rt]x_data are updated but never used
