SLSC Watchdog: Enable system watchdog for ni-slsc-12001

Using cadence watchdog to allow system to reboot when hangs for more
than 10 sec.

- Using phandle reference @watchdog0 to add reset-on-timeout property
  to cadence watchdog in ni-slsc-12001.dts

- Regenerate nati-slsc-defconfig with savedefconfig to clear some
  previous manual edits. And add cadence watchdog driver support.
