[kvm-unit-tests PATCH] powerpc: Make code compilable with -Wmissing-prototypes

[Thomas Huth <thuth@redhat.com>]

It's always better to check whether the implementations match the
prototypes, so make the code compilable with the -Wmissing-prototypes
compiler flag. (However, the flag is not turned on yet since the other
architectures are not ready for this yet)
