Add support for detection of Intel Emerald Rapids processor based on
CPU model.

Emerald Rapids Xeon processors with the model set to
INTEL_EMERALDRAPIDS_X. The data field for this entry is "emr".

Tested the patch series with AST2600 BMC with 5S Intel Emerald Rapids
processors & verified by reading cpu & dimm temperature which matches
host sensor values from lmsensors.
