Create a device hash to match standard device names to types.
Cleanup E_EVENT_ACPI (add missing ones, remove not needed ones).
Actually parse out the ACPI data which we receive.

You can now actually use this ACPI code for event listening, but the
Status field of the event structure needs sanatizing yet (turn into
something meaningful).
