stm32 uart: fix `flush` for non usart_v4 variants
Byte was written to TDR and right after that waker was called. This means `flush` would see that `tx_buf` is empty and can return Ready although actually hardware was still writing this last byte to the wire.
With this change non `usart_v4 ` variants would also use TC interrupt to check when last byte was sent out.
