platform/x86: wmi: Mark GUID-based WMI interface as deprecated
The WMI driver core supports a more mordern bus-based interface for interacting with WMI devices. The older GUID-based interface depends on each WMI GUID and notification id being unique on a given system, which turned out is not the case. Mark the older interface as deprecated since new WMI drivers should use the bus-based interface to avoid this issues.
