After discussion with the devicetree maintainers we agreed to not extend lists with the generic compatible "apple,wdt" anymore [1]. Use "apple,t8103-wdt" as base compatible as it is the SoC the driver and bindings were written for. The block on the Apple M2 Pro/Max/Ultra SoCs is compatible with the existing driver so add its per-SoC compatible.
