hwmon: (coretemp) fix reading of microcode revision (v2)
According to the documentation, simply reading the respective MSR
isn't sufficient: It should be written with zeros, cpuid(1) be
executed, and then read (see arch/x86/kernel/cpu/intel.c for an
example).
v2: Fail probe when microcode revision cannot be determined, but is
needed to check for proper operation.
