Devices that are known to support the WMI thermal interface do not
support the legacy LED control interface. Make `.num_zones = 0` and
avoid calling alienware_zone_init() if that's the case.
Verified by reading the ACPI tables of all supported devices.
Fixes: 9f6c43041552 ("alienware-wmi: added platform profile support")
Fixes: 1c1eb70e7d23 ("alienware-wmi: extends the list of supported models")
