serial: blackfin: Fix CTS flow control
blackfin uart port drivers mistakenly set the struct uart_port flags bit UPF_BUG_THRE (which only has meaning to the 8250 core) while trying to set ASYNC_CTS_FLOW. Uart port drivers can override termios settings based on actual hardware support in their .set_termios method; the serial core sets the appropriate port flags based on the overrides. Overriding only the initial termios settings is accomplished by only perform those overrides if the old termios parameter is NULL.
