Make the touchscreen work on samsung-gts210vewifi
Created by: k-laus
touchscreen works now :-) Had to use ATTRS{name}=="sec_touchscreen" instead of ENV{DEVNAME}=="/dev/input/event2" which solved
- detection problem on cold-booting: touchscreen was not detected/activated at all, only was activated if booted via TWRP Reboot>System
- touchscreen was falsely detected as touchpad
