s390/uv: add prot virt guest/host indication files
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.
