gpiolib: acpi: Add quirk to ignore EC wakeups on HP x2 10 CHT + AXP288 model
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.
