imx6q: add rtscts flag to uart 2
Without this flage the following command will not work.
stty -F /dev/ttymxc2 crtscts
stty: /dev/ttymxc2: cannot perform all requested operation
Fix:
root@phyFLEX-i:~ stty -F /dev/ttymxc2 -a
speed 9600 baud;stty: /dev/ttymxc2
intr = ^C; quit = ^\; erase = ^?; kill = ^U; eof = ^D; eol = <undef>;
eol2 = <undef>; start = ^Q; stop = ^S; susp = ^Z; rprnt = ^R; werase = ^W;
lnext = ^V; flush = ^O; min = 1; time = 0;
-parenb -parodd cs8 hupcl -cstopb cread clocal -crtscts
^^^^^^
