This behavior matches the ACPI specification in ACPI 6.4 section 4.8.3.1.1.2 which describes that the AML handler would generate a Notify() with a code of 0x2 to indicate it was responsible for waking the system. This currently doesn't work because acpi_button_add() only configured `ACPI_DEVICE_NOTIFY` which means that device handler notifications 0x80 through 0xFF are handled. To fix the wakeups on such systems, adjust the ACPI button handler to use `ACPI_ALL_NOTIFY` which will handle all events 0x00 through 0x7F.
