xtensa: replace IOCTL code definitions with constants

This fixes userspace code that builds on other architectures but fails
on xtensa due to references to structures that other architectures don't
refer to. E.g. this fixes the following issue with python-2.7.8:

  python-2.7.8/Modules/termios.c:861:25: error: invalid application
     of 'sizeof' to incomplete type 'struct serial_multiport_struct'
     {"TIOCSERGETMULTI", TIOCSERGETMULTI},
  python-2.7.8/Modules/termios.c:870:25: error: invalid application
     of 'sizeof' to incomplete type 'struct serial_multiport_struct'
     {"TIOCSERSETMULTI", TIOCSERSETMULTI},
  python-2.7.8/Modules/termios.c:900:24: error: invalid application
     of 'sizeof' to incomplete type 'struct tty_struct'
     {"TIOCTTYGSTRUCT", TIOCTTYGSTRUCT},
