    haswell: calibrate 24MHz clock against BCLK
    On haswell ULT systems there is a 24MHz clock that continuously runs
    when deep package c-states are entered. The 100MHz BCLK is shut down
    in the lower c-states. When the package wakes back up a conversion
    formula needs to be applied. The 24MHz calibration is done using the
    internal PCODE unit.
