KVM: PPC: MPIC: Add support for KVM_IRQ_LINE
Now that all pieces are in place for reusing generic irq infrastructure,
we can copy x86's implementation of KVM_IRQ_LINE irq injection and simply
reuse it for PPC, as it will work there just as well.
[stuart: removed line status arg from kvm_vm_ioctl_irq_line and
kvm_set_irq as the arg doesn't exist in 3.8]
