serial: add a new helper function
In most of the time, the driver needs to check if the cts flow control is enabled. But now, the driver checks the ASYNC_CTS_FLOW flag manually, which is not a grace way. So add a new wraper function to make the code tidy and clean. Signed-off-by: Huang Shijie <shijie8@gmail.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
