APT reports that touching the bottom part on ravelin IDP device sometimes
cannot get any response. From vendor's feedback, focaltech touch FW is
supporting 10 fingers, while our touch driver is limiting it to 5. The
mismatch will lead to touch insensitivity issue. As tested, increasing
the max supporting finger num to 10 to match with touch FW can fix this
issue.
