Cascadelake-SP is looked as the second generation Intel XEON processor
scalable family while Skylake-SP is the first generation. Both
Skylake-SP and Cascadelake-SP has the same family (6h) and model (55h),
but with difference stepping number.

In the process of identifying candidate CPU, the stepping number is not
irrelevant any more. The CPU refresh from Skylake-SP to Cascadelake-SP
is this kind of example.

These two patches firstly introduce the stepping number as another factor
to identify future Intel CPU, then introduce the Cascadelake-SP cpu model.

  cpu: Add x86 stepping number as another factor to find candidate CPU
  cpu_map: Add Cascadelake Server CPU model
