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 this is the SoC the
driver and bindings were originally written for.
The t602x (M2 Pro/Max/Ultra) devicetrees submitted in [2] use this
compatible as fallback instead of "apple,t8103-nvme-ans2".
