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.
