soc: raptor_lake: Disable watchdog by default

Without status line, watchdog is enabled by default. The desired
behaviour is to have it disabled and enable only when watchdog
is used, with overlay files. The same way how it is done for
samples/drivers/watchdog and tests/drivers/watchdog/wdt_basic_api.
