Merge branch 'kvm-sev-es-ghcbv2' into HEAD

While the main additions from GHCB protocol version 1 to version 2
revolve mostly around SEV-SNP support, there are a number of changes
applicable to SEV-ES guests as well. Pluck a handful patches from the
SNP hypervisor patchset for GHCB-related changes that are also applicable
to SEV-ES.  A KVM_SEV_INIT2 field lets userspace can control the maximum
GHCB protocol version advertised to guests and manage compatibility
across kernels/versions.
