	  Set initial timeout value for IWDG in ms if enabled at boot.

	  The min timeout supported is 1 ms. The max timeout depends on the
	  MCU's LSI clock frequency and can be calculated with:

	    max. prescaler value (256) * max. reload ticks (4096) / LSI freq.

	  Limiting maximum timeout to a safe value of 26214 ms here, which was
	  calculated for highest LSI frequency among STM32 MCUs of 40 kHz.
