soc/intel: Remove INTEL_CAR_NEM_ENHANCED_V2 config option
SF Mask MSRs' Programming which was done under this config selection will be moved under a new config option called CAR_HAS_SF_MASKS. This segregates the eNEM programming sequence based on sub features supported in each processor. Bug=b:171601324 BRANCH=volteer Test=Build volteer build and boot on Delbin EVT.
