soc/intel/xeon_sp: Refactor code to allow for additional CPUs types
Refactor the code and split it into Xeon common and CPU-specific code. Move most Skylake-SP code into skx/ and keep common code in the current folder. This is a preparation for future work that will enable next generation server CPU. TEST=Tested on OCP Tioga Pass. There does not seem to be degradation of stability as far as I could tell.
