USB: ftdi_sio: revert "USB: ftdi_sio: fix DTR/RTS line modes"
This reverts commit 6a1a82df91fa0eb1cc76069a9efe5714d087eccd.
RTS and DTR should not be modified based on CRTSCTS when calling
set_termios.
Modem control lines are raised at port open by the tty layer and should stay
raised regardless of whether hardware flow control is enabled or not.
This is in conformance with the way serial ports work today and many
applications depend on this behaviour to be able to talk to hardware
implementing hardware flow control (without the applications actually using
it).
Hardware which expects different behaviour on these lines can always
use TIOCMSET/TIOCMBI[SC] after port open to change them.
