Log message:
vmm(4) provides VMSA for AMD SEV-ES
For SEV-ES the hypervisor has to provide a VM Save Area (VMSA). It
will be used by the CPU to load and store encrypted guest CPU state.
Also supply a helper function to retrieve the physical address of
the VMSA. Non SEV-ES VMs are not affected by this change.
