After discussion with the devicetree maintainers we agreed to not extend lists with the generic compatible "apple,nvme-ans2" anymore [1]. Add "apple,t8103-nvme-ans2" as fallback compatible as it is the SoC the driver and bindings were written for. Invert the condition for the 2 or 3 power-domains check to allow using "apple,t8103-nvme-ans2" as base compatible. "apple,t6020-nvme-ans2" on Apple M2 Pro/Max/Ultra SoCs is compatible with "apple,t8103-nvme-ans2" so add its per-SoC compatible.
