Add soc power management for the STM32F4x chips. One low power state is added supported by all chips from the family - the Stop mode with voltage regulator in low-power mode. The Stop mode for STM32F chips has to work with the IDLE timer - CORTEX_M_SYSTICK_IDLE_TIMER, because PLL and HSI are disabled in the Stop mode (Systick is not clocked). The only possible wakeup source is RTC, which works as a IDLE timer for the Systick. The exit latency may need to be adjusted per system, depending on the system tick frequency and other variables.
