dt-bindings: apple,aic2: Add CPU PMU per-cpu pseudo-interrupts 



Advertise the two pseudo-interrupts that tied to the two PMU
flavours present in the Apple M1 Pro/Max/Ultra SoC.

We choose the expose two different pseudo-interrupts to the OS
as the e-core PMU is obviously different from the p-core one,
effectively presenting two different devices.

Imported from "apple,aic".
