Robin Murphy dcbee1061a perf/arm-cmn: Initialise cmn->cpu earlier
commit 597704e201 upstream.

For all the complexity of handling affinity for CPU hotplug, what we've
apparently managed to overlook is that arm_cmn_init_irqs() has in fact
always been setting the *initial* affinity of all IRQs to CPU 0, not the
CPU we subsequently choose for event scheduling. Oh dear.
