The Apple M2 SoC uses AICv2 and is compatible with the existing driver.
Add its per-SoC compatible.
Since multi-die versions of the M2 are not expected decrease
'#interrupt-cells' to 3 for apple,t8112-aic. This is seamlessly handled
inside the driver.

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".

This new incompatible revision of the AIC peripheral introduces
multi-die support. This binding is based on apple,aic, but
changes interrupt-cells to add a new die argument.
Also adds a second reg entry to specify the offset of the event
register. Inexplicably, the capability registers allow us to compute
other register offsets, but not this one. This allows us to keep
forward-compatibility with future SoCs that will likely implement
different die counts, thus shifting the event register. Apple also
specify the offset explicitly in their device tree...
