    mainboard/google/reef: Set PL1 override to 12000mW
    
    Reef is using APL SoC SKU's with 6W TDP max. We've done
    experiments and found the energy calculation is wrong with
    the current VR solution. Experiments show that SoC TDP max
    (6W) can be reached when RAPL PL1 is set to 12W. Therefore,
    we've inserted 12W override after reading the fused value (6W)
    so that the system can reach the right performance level.
    
    BUG=chrome-os-partner:56922
    TEST=webGL performance(fps) not impacted before and after S3.
