parentpowerpc/watchdog: Make use of watchdog_nmi_probe() (diff)

watchdog/core: Rename some softlockup_* functions
The function names made sense up to the point where the watchdog (re)configuration was unified to use softlockup_reconfigure_threads() for all configuration purposes. But that includes scenarios which solely configure the nmi watchdog. Rename softlockup_reconfigure_threads() and softlockup_init_threads() so the function names match the functionality.
