Subject: [PATCH] Input: sentelic - only report position of first finger as ST
 coordinates

commit a25461659050b913e114d282bf58823682eb56b6 upstream.

Report only the position of the first finger as absolute non-MT coordinates,
instead of reporting both fingers alternatively. Actual MT events are
unaffected.

This fixes horizontal and improves vertical scrolling with the touchpad.
