input: touchscreen: sec_ts: reset touch to neutral state when releasedandroid-11.0.0_r0.57android-11.0.0_r0.56android-11.0.0_r0.47android-11.0.0_r0.46android-11.0.0_r0.33android-11.0.0_r0.32android-msm-redfin-4.19-android11-qpr1android-msm-bramble-4.19-android11-qpr1

touch_offload slots were left with non-zero pressure and size when
(un)locked_release_all_finger was called during suspend. Reset these
fields to zero and report pressure=0 as part of releasing touches.
