How can you set open only mode without opening /dev/watchdog?

You cannot, as WDT_MPC8XX_OPEN_ONLY is an ioctl().

Could anybody direct me to an example of a simple watchdog application using the regular API?

unsigned int timeout=300; /* set watchdog timeout to 5 minutes */ ... write (fd, &timeout, sizeof(timeout));

Ummm.... all this has nothing to do with U-Boot and is off topic on this mailing list.
