sensors: Dont add DTS sensors when OCC inband sensors are available
There are two sets of core temperature sensors today. One is DTS scom
based core temperature sensors and the second group is the sensors
provided by OCC. DTS is the highest temperature among the different
temperature zones in the core while OCC core temperature sensors are
the average temperature of the core. DTS sensors are read directly by
the host by SCOMing the DTS sensors while OCC sensors are read and
updated by OCC to main memory.
Reading DTS sensors by SCOMing is a heavy and slower operation as
compared to reading OCC sensors which is as good as reading memory.
So dont add DTS sensors when OCC sensors are available.
