[lm-sensors] Only coretemp is found by sensors-detect

Chris,

I contacted SMSC but they won't give out the datasheets since those
are DELL specific components and I'm an HP person :-)

The only other thing I can suggest is to take register dumps (i2cdump)
when the machine is idle and when the CPU is busy and the fans
spinning (faster). Then we can take a look at what register values
changed and compare it with currently supported chips to find a
possible compatible match.
