ARM: xen: validate hypervisor compatible before parsing its version
fdt_find_hyper_node() reads the raw compatible property and then derives
hyper_node.version from a prefix match before later printing it with %s.
Flat DT properties are external boot input, and this path does not prove
that the first compatible entry is NUL-terminated within the returned
property length.
Keep the existing flat-DT lookup path, but verify that the first
compatible entry terminates within the returned property length before
deriving the version suffix from it.
