dt-bindings: interrupt-controller: apple,aic2: Add AICv3

AIC version 3 as found on the Apple M3 (t8122) is very similar to AICv2 in
its base functionality. It can use the same device tree bindings as AICv2
so add it to the AICv2 bindings. This interrupt controller is used on all
Apple SoCs starting with M3 up to at least M5.

The only apparent difference is the increased IRQ config offset. Apple's
device tree codes this new offset as property of the "aic" node but the
value stayed constant for all SoCs with "aic,3". Since the SoC specific
compatible "apple,t8122-aic3" will be only used in the driver this offset
can remain a driver implementation detail.
