peci: cpu: Add Intel Sapphire Rapids support

Add support for detection of Intel Sapphire Rapids processor based on
CPU family & model.

Sapphire Rapids Xeon processors with the family set to 6 and the
model set to INTEL_FAM6_SAPPHIRERAPIDS_X. The data field for this entry
is "spr".

Tested the patch series with AST2600 BMC with 4S Intel Sapphire Rapids
processors & verified by reading cpu & dimm temperature.
