dt-bindings: apple,aic: Add affinity description for per-cpu pseudo-interrupts

Some of the FIQ per-cpu pseudo-interrupts are better described with
a specific affinity, the most obvious candidate being the CPU PMUs.

Augment the AIC binding to be able to specify that affinity in the
interrupt controller node.
