mb/google/volteer: Configure IA32_L3_MASK_x MSRs for L3 CQOS
Selecting USE_CAR_NEM_ENHANCED_V1 as of now. This selection in Kconfig
programs IA32_L3_MASK_1 (0xc91) & IA32_L3_MASK_2 (0xc92). These will
select ways for eviction & non-eviction. TGL will have to switch back
to USE_CAR_NEM_ENHANCED_V2 once the IA32_L3_SF_MASK_1 (0x1891) &
IA32_L3_SF_MASK_2 (0x1892) programming requirements are understood.
Bug=b:171601324
BRANCH=volteer
Test=Build coreboot for volteer. Boot on SKU that has 4MB L3 cache.
