dt-bindings: interrupt-controller: apple,aic2: Add apple,t8112-aic compatible
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.
