kmini3g: input: abov_touchkey- Disable Samsung Dual Detect

Samsung has introduced this since Lollipop Release and due to this the Capacitive Keys had issues and stopped working repeatedly once screen is locked.
It only works again after reboot and fails after screen is locked.
Disabling this has fixed Capacitive Key Issue.
