STM32 reset type judgment and software reset bug

STM 32 has a serious BUG when resetting:

1. The power-on reset and the external watchdog chip reset cannot be distinguished! RCC_FLAG_BORRST, RCC_FLAG_PINRST, RCC_FLAG_LPWRRST are all reset!

2. In this way, when the key code is initialized during power-on reset, these codes do not need to be restarted when the watchdog is reset. This key code will cause abnormal application business! If the two interrupts are inseparable, the system abnormality will affect the business when the watchdog is reset!

/*
RCC_FLAG_BORRST: POR/PDR or BOR reset //Power-on/power-down reset (POR/PDR reset) or brownout (BOR) reset
RCC_FLAG_PINRST: Pin reset //NRST pin may be watchdog reset
RCC_FLAG_PORRST: POR/PDR reset
RCC_FLAG_SFTRST: Software reset
RCC_FLAG_IWDGRST: Independent Watchdog reset
RCC_FLAG_WWDGRST: Window Watchdog reset
RCC_FLAG_LPWRRST: Low Power reset
