  coretemp: Only log critical temperature events

    According to the Intel manual
    https://www.intel.com/content/dam/www/public/us/en/documents/manuals/64-ia-32-architectures-software-developer-vol-3b-part-2-manual.pdf
    the Thermal Status (0) and Thermal Status Log (1) bits report only a
    high temperature on the CPU, not a critical temperature as suggested in
    the coretemp driver. Check the Critical Temperature Log (5) instead.
    The critical temperature waives guarantees of correct function,
    therefore the CPU could have for example written some wrong values into
    memory at that point and the OS should be stopped ASAP as the state is
    no longer reliable.
