We can only use CONFIG_PPC_DOORBELL to control whether
the doorbell exception should be enabled.

Thanks, applied to kvm-ppc-queue with a slightly changed patch description:

    KVM: PPC: Guard doorbell exception with CONFIG_PPC_DOORBELL

    Availablity of the doorbell_exception function is guarded by
    CONFIG_PPC_DOORBELL. Use the same define to guard our caller
    of it.
