soc/intel: Add Intel Xeon Scalable Processor support
This patch adds support for Intel Xeon-SP.
This patch is developed and verified with Skylake Scalable
Processor, which is a processor in Xeon-SP family. The code
is expected to be reusable for future geneations of Xeon-SP
processors, and will be updated with smaller targeted
patches accordingly, to add support for additional Xeon-SP
processors, to add features, and to improve the code base.
The Skylake-SP FSP is based on FSP 2.0. The FSP is a
proof-of-concept build. The binary is not shared in public,
when this patch is upstreamed.
