soc/amd/cezanne: clean up global NVS 

From Cezanne on, the TMPS, TCRT and TPSV fields are unused in both the C
and ACPI code, so they can be removed. Also remove the unused fields
that were previously used for PCNT and PWRS. The LIDS field is only used
in the ACPI code, but keep if for now, since it would require a bigger
rework to remove it from the global NVS.
