platform/x86: wmi: Pass event data directly to legacy notify handlers

The current legacy WMI handlers are susceptible to picking up wrong
WMI event data on systems where different WMI devices share some
notification IDs.

Prevent this by letting the WMI driver core taking care of retrieving
the event data. This also simplifies the legacy WMI handlers and their
implementation inside the WMI driver core.
