mxs: uart: fix setting RTS from software With the patch "serial: mxs-auart: fix the wrong RTS hardware flow control" the mainline mxs-uart driver now sets RTSEN only when hardware flow control is enabled via software. It is not possible any longer to set RTS manually via software. However, the manual modification is a valid operation. Regain the possibility to set RTS via software and only set RTSEN when hardware flow control is explicitly enabled via settermios cflag CRTSCTS.
