hwmon: (coretemp) Add TjMax detection for mobile CPUs

Following patch will finally solve the detection of Intel Mobile CPUs which
share same CPUID with Desktop/Server CPUs. We need this information to test
some bit so we know if TjMax is 100C or 85C. Intel claims this works for mobiles
only, respect that and set for desktops the TjMax to 100C. Intel provided some
table on their wiki based on my chat with them at:
