[WATCHDOG] correct sysfs name for watchdog devices

While looking for possible candidates for our udev.rules package,
I found a few odd ->name properties. /dev/watchdog has minor 130
according to devices.txt. Since all watchdog drivers use the
misc_register() call, they will end up in /sys/class/misc/$foo.
udev may create the /dev/watchdog node if the driver is loaded.
I dont have such a device, so I cant test it.
The drivers below provide names with spaces and even with / in it.
Not a big deal, but apps may expect /dev/watchdog.
