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]
BUG=chrome-os-partner:48412
