A bit follow up on this patch.
When user turned on the watchdog on
u-boot-xxxx.dts while having the original
setup triggers the SDRAM calibration fail.

While users those do not turn on the watchdog.
w/o this patch could be fine and not sure
what is  the proper way to link the dts and
watchdog driver accordingly.

Always included the watchdog driver should
not be harm (correct me if not).
What the dts does can either initialize it or not.
What w/o the driver and dts setting to "okay"
does break things.

So Tom I am not sure based on your experiences.
Always attach driver and leave dts to do the job?
