KVM: PPC: Book3S HV: Counters for passthrough IRQ stats
Add VCPU stat counters to track affinity for passthrough
interrupts.
pthru_all: Counts all passthrough interrupts whose IRQ mappings are
in the kvmppc_passthru_irq_map structure.
pthru_host: Counts all cached passthrough interrupts that were injected
from the host through kvm_set_irq (i.e. not handled in
real mode).
pthru_bad_aff: Counts how many cached passthrough interrupts have
bad affinity (receiving CPU is not running VCPU that is
the target of the virtual interrupt in the guest).
