touchpad: disable MT for elantech semi-mt touchpads

When three fingers are set down on the touchpad, one finger tends to get a 0/0
coordinate, triggering palm detection in the upper left corner. Handle this
like the jumping semi-mt touchpads and disable MT handling and instead
just rely on the x/y axis and the BTN_TOOL_* events.
