ACPI: scan: Use acpi_setup_gpe_for_wake() for buttons
After starting to use platform devices for representing buttons
enumerated via ACPI, acpi_mark_gpe_for_wake() is insufficient for
preparing their GPEs to wake up the system from sleep because it
does not change the "dispatch type" of the given GPE to
ACPI_GPE_DISPATCH_NOTIFY. Subsequently, this causes acpi_enable_gpe()
in __acpi_device_wakeup_enable() to fail and system suspend transitions
to be aborted.
Address this by updating acpi_wakeup_gpe_init() to use
acpi_setup_gpe_for_wake() for buttons like for any other devices.
This allows acpi_setup_gpe_for_wake() to be simplified further because
buttons are not a special case in it any more, so do that as well.
Fixes: 52d8640196 ("ACPI: button: Convert the driver to a platform one")
