intel/skylake: Implement native Cache-as-RAM (CAR)
Now coreboot should do BIOS CAR setup along with NEM mode setup.
This patch also provides a mechanism to use 16MB code caching benefit although LLC still limited to 1M/1.5M based on SOC LLC limit. Here with unlimited cache line gets replaced. Now we could use unlimited cache size along with well defined data size
