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.
