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。

[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.
