platform/x86: intel-hid: Power button suspend on Dell Latitude 7275
On Dell Latitude 7275 the 5-button array is not exposed in the ACPI tables, but notififies are still sent to the Intel HID device object (device ID INT33D5) in response to power button actions. They were ignored as the intel-hid driver was not prepared to take care of them until recently. Power button wakeup from suspend-to-idle was added in: commit 635173a1 ("intel-hid: Wake up Dell Latitude 7275 from suspend-to-idle") However power button suspend doesn't work yet on this platform so it would be good to add it also. On the affected platform (for which priv->array is NULL), add a new upfront check against the power button press notification (0xCE) to notify_handler(), outside the wakeup mode this time, which allows reporting the power button press event and triggers the suspend. Also catch and ignore the corresponding power button release notification (0xCF) to stop it from being reported as an "unknown event" in the logs.
