  i386: Update stepping of Cascadelake-Server

Update the stepping from 5 to 6, in order that
the Cascadelake-Server CPU model can support AVX512VNNI
and MSR based features exposed by ARCH_CAPABILITIES.

  i386: Enable NPT and NRIPSAVE for AMD CPUs

Modern AMD CPUs support NPT and NRIPSAVE features and KVM exposes these
when present. NRIPSAVE apeared somewhere in Opteron_G3 lifetime (e.g.
QuadCore AMD Opteron 2378 has is but QuadCore AMD Opteron HE 2344 doesn't),
NPT was introduced a bit earlier.

Add the FEAT_SVM leaf to Opteron_G4/G5 and EPYC/EPYC-IBPB cpu models.
