Bug in HAL_IWDG_DEFAULT_TIMEOUT

[Kira-sempai]

https://github.com/STMicroelectronics/STM32CubeF2/blob/cfa4386ba4eaae35dea33e09bac39b87480345ad/Drivers/STM32F2xx_HAL_Driver/Src/stm32f2xx_hal_iwdg.c#L124

Probably should be #define HAL_IWDG_DEFAULT_TIMEOUT (((6UL * 256UL * 1000UL) / LSI_VALUE) + ((LSI_STARTUP_TIMEOUT / 1000UL) + 1UL))

BTW, can't find it's definition in stm32f2xx_hal_conf_template.h

Hi @Kira-sempai,

Thank you for your contribution. The point you reported is related to a typo in the comment description. Indeed, a fix in the comment below : https://github.com/STMicroelectronics/STM32CubeF2/blob/cfa4386ba4eaae35dea33e09bac39b87480345ad/Drivers/STM32F2xx_HAL_Driver/Src/stm32f2xx_hal_iwdg.c#L121-L123 will be updated and made available in future release looks like the following:

  The timeout value is multiplied by 1000 to be converted in milliseconds.
- LSI startup time is also considered here by adding LSI_STARTUP_TIMEOUT
+ LSI startup time is also considered here by adding LSI_STARTUP_TIME
   converted in milliseconds. 

Concerning the define of the LSI_STARTUP_TIME, you can find it in the include files of the CMSIS device.

Thank you once again for your contribution.
