Indeed, GICv3 support is needed the moment it is brought up on a GIC v3 based machine. Can be tested on qemu if told to emulate V3.
GICv3 is pretty close to 2, but different enough that it's worth making a copy of the v2 driver and modifying it.

We made a gicv3 driver for zircon, so probably simpler to just back port it from there.
