ec/google/wilco: Fix ACPI power status events
This change fixes the power status events for AC and battery
events from the EC. The register that was being used is not
returning the expected information.
BUG=b:125472740
TEST=enable ACPI debug in the kernel and verify that AC and
battery insert/remove are detected properly.
