    soc/intel/skylake: Add _ACx methods for TSR0 sensor for fan control
    
    This patch updates below info,
    [1] Delete the DPTF_CPU_ACTIVE_AC* values because these are not
    being used. Hence, removing unnecessary defines.
    [2] Add new DPTF_TSR0_ACTIVE_AC* temperature trip points for TSR0
    external thermal sensor. These trip points are being used by _ACx
    methods to control the fan speed on Skylake-U fan based Lars and
    Kunimitsu platforms.
    [3] Follow up patches are using DPTF_CPU_ACTIVE_AC* temperature trip
    points in board specific acpi/dptf.asl (for lars, kunimitsu, etc) to
    control the fan speed as per the CPU temperature trip points.
    [4] Newly added _ACx methods for thermal sensor TSR0 in this patch
    has nothing to do with DPTF_CPU_ACTIVE_AC*.
    
    We can control fan speed using various different thermal sensors.
    In this patch, we have added new _ACx methods for TSR0 thermal sensor.
    We run the fan at different speeds to cool down the system at different
    TSR0 temperatures.
    
    Similarly, we considered CPU sensor temperature values and ran the fan
    at different speeds to cool down the system.
    
    BUG=chrome-os-partner:51025
    BRANCH=firmware-glados-7820.B
    TEST=Built and booted on kunimitsu and lars EVT boards.
    Verified these _ACx methods with _ART table on these boards
    with different workloads.
