watchdog: clean up some function names and arguments
Rename the update_timers*() functions to update_watchdog*().
Remove the boolean argument from watchdog_enable_all_cpus() because
update_watchdog_all_cpus() is now a generic function to change the run
state of the lockup detectors and to have the lockup detectors use a new
sample period.
