This series adds support for enabling VMSA SEV features for SEV-ES and
SEV-SNP guests. Since that is already supported for IGVM files, some of
that code is moved to generic path and reused.

Debug-swap is already supported in KVM today, while patches for enabling
Secure TSC have been accepted for the upcoming kernel release.

Roy,
I haven't been able to test IGVM, so would be great if that is tested to 
confirm there are no unintended changes there.

Changes since v1 (*):
- Move patch enabling use of KVM_SEV_INIT2 for SEV-ES guests before 
  patch enabling use of debug-swap VMSA SEV feature (Tom)
- Only issue KVM_SET_TSC_KHZ if user has specified a tsc-frequency for 
  Secure TSC (Tom)
- Patch 9/9 is new and refactors check_sev_features in preparation for 
  future SEV feature support (Tom)
- Minor updates to commit log and comments (Tom)
- Collect review tags from Tom
