irqchip/apple-aic: Add support for the Apple Interrupt Controller
This is the root interrupt controller used on Apple ARM SoCs such as the
M1. This irqchip driver performs multiple functions:
* Handles both IRQs and FIQs
* Drives the AIC peripheral itself (which handles IRQs)
* Dispatches FIQs to downstream hard-wired clients (currently the ARM
timer).
* Implements a virtual IPI multiplexer to funnel multiple Linux IPIs
into a single hardware IPI
