Do a RPM put if watchdog is not already started during probe and re

On K3 SoCs, watchdogs and their corresponding CPUs are under same PD, so
if the reference count of unused watchdogs aren't dropped, it will lead
to CPU hotplug failures as Device Management firmware won't allow to
turn off the PD due to dangling reference count.

I always find it amazing that people think everyone would understand the TLAs
(three-letter-acronyms) they use. While those who don't might find it confusing
why a watchdog driver would need or want to drop rotation-per-minute counts,
and what that has to do with police departments, that isn't worth
arguing about
