Jose Marinho 24a4b87245 ACPICA: Detect GED device and keep track of _EVT 
ACPICA commit dc6fd1d12903015726a8a6f87f63e86141576a68

The GED device is described by a _HID of ACPI0013.
This code traverses the namespace identifying all GED devices.
For each GED device in the namespace we record 1) the Interrupt objects
and the _EVT method.

This information is used when an interrupt is simulate.
