Shreesh Chhabbi 860c68449d src/soc/intel: Add support for CAR_HAS_SF_MASKS and select for TGL 
Program IA32_CR_SF_QOS_MASK_x MSRs under CAR_HAS_SF_MASKS config
option. Select CAR_HAS_SF_MASKS for Tigerlake.

During CAR teardown code, MSRs IA32_L3_MASK_x & IA32_CR_SF_QOS_MASK_x
are not being reset to default as
per the doc NEM-Enhanced-Mode-Whitepaper-Tigerlake-draft-WW46.5.
Resetting the value of IA32_PQR_ASSOC[32:33] to 00b is sufficient.

Bug=b:171601324
BRANCH=volteer
Test=Build and boot to ChromeOS on Delbin.
