We've seen some issues with the x530 under extreme conditions where the
DDR gets into a bad state. Generally this results in an application
crash followed by a lock-up in u-boot.

Enabling the watchdog prevents the lock up and will let the DDR training
have another go. Sometimes this recovers but even a reboot loop is
better than a complete lockup.

Changes in v2:
- update commit message
