The ACPI Generic Event Device (GED) is a hardware-reduced specific device[ACPI v6.1 Section 5.6.9] that handles all platform events, including the hotplug ones. This patch generates the AML code that defines GEDs.
Platforms need to specify their own GED Event bitmap to describe what kind of events they want to support through GED. Also this uses a a single interrupt for the GED device, relying on IO memory region to communicate the type of device affected by the interrupt. This way, we can support up to 32 events with a unique interrupt.
This supports only memory hotplug for now.
