soc/intel/tigerlake: Update Kconfig for NEM Enhanced Mode 

This change switches the selection of CAR mode so that
INTEL_CAR_NEM_ENHANCED_V2 is the default unless mainboard
selects INTEL_CAR_NEM. INTEL_CAR_NEM is selected only by
mainboards using older silicon (ES1 or ES2) that did not
support NEM enhanced mode.

This enables NEM Enhanced Mode for TGL-U/Y RVPs.

Bug=b:171601324
BRANCH=volteer
Test=Build coreboot for volteer. Boot on SKU that has 4MB L3 cache.
