    mainboard/google/snappy: Set PL1 override to 12000mW
    
    Snappy is using APL SoC SKU's with 6W TDP max. As Reef,
    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.
