    apollolake: Set RAPL power limit PL1 value to 12W.
    
    This patch sets tuned RAPL power limit PL1 value to
    12W in acpi/dptf.asl for RAPL MSR register. With PL1
    as 12W for WebGL and stream case, we measured SoC power
    reaching upto 6W. Above 12W PL1 value, we observed that
    Soc power going above 6W. With PL1 as 12W, system is
    able to leverage full TDP capacity.
    
    BUG=chrome-os-partner:56524
    TEST=Built, booted on reef and verifed the package
    power with heavy workload.
