From: Hans de Goede <hdegoede@redhat.com>

commit 11e94f28c3de35d5ad1ac6a242a5b30f4378991a upstream.

Replace the boolean is_smo8500_device variable with an acpi_type enum.

For now this can be either ACPI_GENERIC or ACPI_SMO8500, this is a
preparation patch for adding special handling for the KIOX010A ACPI HID,
which will add a ACPI_KIOX010A acpi_type to the introduced enum.

For stable as needed as precursor for next patch.
