watchdog: sch56xx: Remove unnecessary checks for register changes

Since the watchdog core keeps track of the watchdog's active state, start/stop
will never get called when no changes are necessary. So we can remove the
check for the output_enable register changing before writing it (which is
an expensive operation).
