It might help to instrument acpiecdt_find() to see why the
embedded controller driver doesn't attach early.
Or to check acpidump whether there is a "ECDT" table at all.
Didn't check the spec, but perhaps the assumption in the code
that a ECDT must be present if the EC is needed for device
initialization is just wrong?
