powerpc/kvm: Fix ppc64_defconfig + PPC_POWERNV=n build error
kvm_no_guest() calls power7_wakeup_loss() to put the thread into the
deepest supported idle state. power7_wakeup_loss() is defined in
arch/powerpc/kernel/idle_power7.S, which is compiled only when
PPC_P7_NAP=y.
And PPC_P7_NAP is selected when PPC_POWERNV=y.
Hence in cases where PPC_POWERNV=n and KVM_BOOK3S_64_HV=y we see the
following error:
arch/powerpc/kvm/built-in.o: In function `kvm_no_guest':
arch/powerpc/kvm/book3s_hv_rmhandlers.o:(.text+0x42c): undefined reference to `power7_wakeup_loss'
Fix this by adding PPC_POWERNV as a dependency for KVM_BOOK3S_64_HV.
