    thermal/intel: Introduce Intel TCC library · a3c1f066
    Zhang Rui authored
    There are several different drivers that accesses the Intel TCC
    (thermal control circuitry) MSRs, and each of them has its own
    implementation for the same functionalities, e.g. getting the current
    temperature, getting the tj_max, and getting/setting the tj_max offset.
    
    Introduce a library to unify the code for Intel CPU TCC MSR access.
    
    At the same time, ensure the temperature is got based on the updated
    tjmax value because tjmax can be changed at runtime for cases like
    the Intel SST-PP (Intel Speed Select Technology - Performance Profile)
    level change.
