The Logitech T650 used to report 3 fingers swipes to the up as a press on
the Super key. When we switched the touchpad to the raw mode, we also
disable such firmware gesture and some users may rely on it.
Unfortunately, 3 finger swipes are still not supported in most of the
Linux environments, which means that we disabled a feature of the touchpad.
Allow users to revert the raw reporting mode and keep going with the
firmware gestures by providing a new module parameter.
