[PATCH v2 4/4] gpiolib: acpi: Add quirk to ignore EC wakeups on HP x2 10 CHT + AXP288 model

[Hans de Goede <hdegoede@redhat.com>]

There are at least 3 models of the HP x2 10 models:

Bay Trail SoC + AXP288 PMIC
Cherry Trail SoC + AXP288 PMIC
Cherry Trail SoC + TI PMIC

Like on the other HP x2 10 models we need to ignore wakeup for ACPI GPIO
events on the external embedded-controller pin to avoid spurious wakeups
on the HP x2 10 CHT + AXP288 model too.

This commit adds an extra DMI based quirk for the HP x2 10 CHT + AXP288
model, ignoring wakeups for ACPI GPIO events on the EC interrupt pin
on this model. This fixes spurious wakeups from suspend on this model.
