The commit 3ab1663af6c1 ("watchdog: stm32_iwdg: Add pretimeout support") introduces the support for the pre-timeout interrupt. The support for this interrupt is optional but the driver uses the platform_get_irq() which produces an error message during the driver probe if we don't have any `interrupts` property in the DT. Use the platform_get_irq_optional() API to get rid of the error message as this property is optional.
