Bug Description

[Impact]
4.18+ kernel with Ubuntu 18.04.
libinput 1.10.4-1
xserver-xorg-input-libinput 0.27.1-1
tap-to-click is on by default.
After tapping on SYNA8005 (06CB:CD8C) for 50+ times, touchpad will be no response when tapping.

[Fix]
libinput detect these taps as palm, so permanently disable tap-to-click.
upstream patch of libinput already fixed this issue:

commit 237ebb7cc4e9bf035891176acb08b1bf558ee989
Author: Peter Hutterer <email address hidden>
Date: Mon Jun 25 14:50:22 2018 +1000

    touchpad: don't disable tapping on MT_TOOL_PALM

    The tapping code can handle palm states now, so there is no need to disable
    tapping altogether when a tool-based palm is detected.

    Fixes https://gitlab.freedesktop.org/libinput/libinput/issues/65

    Signed-off-by: Peter Hutterer <email address hidden>

[Test]
Cherry-picked this commit to 1.10.4 and rebuild libinput, tested for thousands of times.
touchpad taping OK.

[Regression Potential]
Low, upstream fix, tested OK.

We need to add a bionic task here to track the fact the fix is missing in bionic. But since I've been told off for doing that in the past, someone else can do it :)
