watchdog: stm32_iwdg: fix error message during driver probe 



The commit 3ab1663a ("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.
