Description of problem:
Emerald Rapids (EMR) is the next Intel Xeon processor after Sapphire
Rapids (SPR).

EMR C-states are the same as SPR C-states, and we expect that EMR
C-state characteristics (latency and target residency) will be the
same as in SPR. Therefore, add EMR support by using SPR C-states table.
