    amdsmn(4), amdtemp(4): add support for AMD Ryzen 7 "Phoenix" processors
    
    Adds support for AMD Ryzen 7 "Phoenix" processors (family 0x19,
    model 0x70-0x7f) to the amdsmn(4) and amdtemp(4) drivers. This
    enables temperature readings of these CPUs via sysctl.
    
    The sensors function identically to those for the "Raphael" processors
    (model 0x60-0x6f); only the PCI device ID differs.
