serial: stm32: add Framing error support

Add management of Bit 1 of USART_ISR = FE: Framing error
This bit is set by hardware when a de-synchronization, excessive noise
or a break character is detected. It is cleared by software, writing 1
to the FECF bit in the USART_ICR register (for stm32 after f4).
