ACPICA: Add support for multiple notify handlers
This change adds support to allow multiple notify handlers on Device, ThermalZone, and Processor objects. Also re-worked and restructured the entire notify support code for handler installation, handler removal, notify event queuing, and notify dispatch to handler. Extends and updates original commit 3f0be67("ACPI / ACPICA: Multiple system notify handlers per device") by Rafael Wysocki.
