Sometimes touchpad automatically trigger double click

[AceLan Kao]

[Impact]
Dell machines which uses goodix touchpad IC emit double click event
while touching the touchpad if designware i2c adapter is in runtime
suspend.

Goodix re-assert the interrupt if host doesn't read the data within
100ms and designware takes a longer time to wake up from runtime
suspend. In the case, it got a second interrupt during resuming, so
it thinks it's a double click.

[Fix]
There is no simple way to fix this, it's a firmware issue and goodix
agrees to fix this in their firmware on next release, but this issue is
still affects the machines that don't come with an updated firmware. So,
add a quirk to mark those machines and avoid the designware from entering
runtime suspend.

[Regression Potential]
Low, it only affects the listed machines, and prevent designware from
entering runtime suspend impacts the power consumption little or none
during short or long idle.

[MISC]
This patch contains on going product name, so set it as SAUCE patch,
will submit it to upstream and to Bionic kernel later.

This bug is awaiting verification that the kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed-disco' to 'verification-done-disco'. If the problem still exists, change the tag 'verification-needed-disco' to 'verification-failed-disco'.

If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed.
