[PATCH v3 4/4] KVM: SVM: Increase supported GHCB protocol version

[Joerg Roedel]

From: Brijesh Singh <brijesh.singh@xxxxxxx>

Now that KVM has basic support for version 2 of the GHCB specification,
bump the maximum supported protocol version. The SNP specific functions
are still missing, but those are only required when the Hypervisor
supports running SNP guests.
