KVM: SVM: Implement VIRT_SPEC_CTRL support for SSBD

commit bc226f07dcd3c9ef0b7f6236fe356ea4a9cb4769 upstream

Expose the new virtualized architectural mechanism, VIRT_SSBD, for using
speculative store bypass disable (SSBD) under SVM.  This will allow guests
to use SSBD on hardware that uses non-architectural mechanisms for enabling
SSBD.

[ tglx: Folded the migration fixup from Paolo Bonzini ]
