From: Mario Limonciello <mario.limonciello@xxxxxxx>
commit a7e23ec17feec ("ACPI: button: Install notifier for system events
as well") modified the ACPI button behavior to send
`ACPI_BUTTON_NOTIFY_WAKE` events. This caused a regression on a
"Dell Optiplex 3040" sending `KEY_POWER` randomly at runtime.
Adjust logic so that the event `ACPI_BUTTON_NOTIFY_WAKE` will never
send `KEY_POWER`.
