Bug description:
[Impact]
On some systems when the system is put to sleep pressing the ACPI power
button will cause the EC SCI to try to wake the system by a Notify(DEV, 0x2)
with an intention to wake the system up from suspend.
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.
[Fix]
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.

Included in linux-next
39bc24ceb09d ACPI: button: Install notifier for system events as well
[Test]
The issue could be found on Dell Pro 14 notebook.
Verify the system could be waken up by the power button.
[Where problems could occur]
ACPI button driver submit more events to wake up the system, it could lead to
unexpected wake up if the BIOS sends unexpected events during suspend.
