Subject: [PATCH] KVM: PPC: add missing MODULE_DESCRIPTION() macros

With ARCH=powerpc, make allmodconfig && make W=1 C=1 reports:
WARNING: modpost: missing MODULE_DESCRIPTION() in arch/powerpc/kvm/test-guest-state-buffer.o
WARNING: modpost: missing MODULE_DESCRIPTION() in arch/powerpc/kvm/kvm-pr.o
WARNING: modpost: missing MODULE_DESCRIPTION() in arch/powerpc/kvm/kvm-hv.o

Add the missing invocations of the MODULE_DESCRIPTION() macro.
