ACPI / EC: Fix a gap that ECDT EC cannot handle EC events
It is possible to register _Qxx from namespace and use the ECDT EC to perform event handling. The reported bug reveals that Windows is using ECDT in this way in case the namespace EC is not present. This patch facilitates Linux to support ECDT in this way.
