cyclades: ioctls cleanup

Browse source

- add a cy_ prefix to functions with changed prototypes
- cy_get_serial_info: initialize serial_struct by initializer,
  save a memset
- inline simple functions (get_mon_info, {s,g}et_default_threshold,
  {s,g}et_default_timeout) directly in the ioctl handler
- add a cy_cflags_changed helper to not copy its code by
  wait_event_interruptible
- remove some ret_val = 0 assignments, it's preset to 0
- TIOCGICOUNT: don't do many put_user's, do one copy_to_user
