Let's export the prot_virt_guest and prot_virt_host variables into the UV sysfs firmware interface to make them easily consumable by administrators. prot_virt_host being 1 indicates that we did the UV initialization (opt-in) prot_virt_guest being 1 indicates that the UV indicates the share and unshare ultravisor calls which is an indication that we are running as a protected guest.
