    lenovo/x201: run `enable acpi` smi before s3 resume
    
    Fixes missing ec event bug.
    After multiple suspend-resume cycle no EC event are processed
    because the EC doesn't notice the OSPM anymore.
    
    Calling the acpi resume handler fix this mainly by calling:
    ec_write(0x80, 0x01); /* discard all events, and enable attention */
