mqb 19448a920c 修改了GPIO_Configuration
STM32F4系列UART在初始化的时候,如果GPIO_AF放到GPIO_INIT后边,系统复位后,串口会向外发送一个字节的数据,通常是0x00。将GPIO_AF放到GPIO_INIT前边可以避开这个问题。

ItsEddy ced7d5a34f [DeviceDriver] stm32: Remove explicity clear of RXNE flag
According to STM32 Manual, the USART RXNE flag will be clear automatically after
read to the USART_DR register[1], so the call to USART_ClearITPendingBit is
unnecessary.
