[coreboot-gerrit] Change in coreboot[master]: intel/common: CAR setup CQOS

[Naresh Solanki (Code Review)]

Change subject: intel/common: CAR setup CQOS

intel/common: CAR setup CQOS

Enable CQOS on Geminilake.

In Apololake, CBM_LEN is 0x7. Whereas the same in Geminilake is 0xF.

Thus get CBM_LEN using cpuid instruction & generate CBM_LEN_MASK.

Later use the CBM_LEN_MASK when writing to IA32_L2_MASK_* to set right
bits.

BUG=None
TEST= Build for Geminilake platform i.e., glkrvp & check for successful
CAR setup. Even verified the same on APL platform i.e., on Reef
