[PATCH v11 32/35] KVM: SVM: Add module parameter to enable the SEV-SNP

[Michael Roth]

From: Brijesh Singh <brijesh.singh@xxxxxxx>

Add a module parameter than can be used to enable or disable the SEV-SNP
feature. Now that KVM contains the support for the SNP set the GHCB
hypervisor feature flag to indicate that SNP is supported.
