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

[pg: updated to current upstream #defines]
