serial: jsm: Replace magic value with the proper define
The changed function flushes the tx UART and the '4' corresponds to the UART_FCR_CLEAR_XMIT value. This commit replaces the magic number with this define. Signed-off-by: Konrad Zapalowicz <bergo.torino@gmail.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
