commit 1796f808e4bb ("HID: i2c-hid: acpi: Stop setting wakeup_capable")
changed the policy such that I2C touchpads may be able to wake up the
system by default if the system is configured as such.
However for some devices there is a bug, that is causing the touchpad to
instantly wake up the device again once it gets deactivated. The root cause
is still under investigation:
https://lore.kernel.org/linux-acpi/2d983050-f844-6c5e-8ae9-9f87ac68dfdd@xxxxxxxxxxxxxxxxxxx/T/#mb2e738787f6b6208d17b92aa6e72d4de846d4e4d
To workaround this problem for the time being, introduce a quirk for this
model that will prevent the wakeup capability for being set for GPIO 16.
