    intel/skylake: Add devicetree settings for acoustic noise mitigation
    
    Add options to the skylake chip config that will allow tuning the
    various settings that can affect acoustics with the CPU and its VRs.
    
    These settings are applied inside FSP, and they can adjust the slew
    slew rate when changing voltages or disable fast C-state ramping on
    the various CPU VR rails.
    
    BUG=b:35581264
    BRANCH=none
    TEST=these are currently unused, but I verified that enabling the
    options can affect the acoustics of a system at runtime.
