dt-bindings: iommu: dart: Add apple,t6020-dart compatible
t6020-dart is compatible to t8110-dart and annotated as such in Apple's
device tree. Add its per-SoC compatible in case t6020 specific handling
becomes necessary. The dart instances on M2 Pro/Max/Ultra based SoCs
differ in one aspect from the M2 based ones. They indicate an IAS of 42
requiring implementing support for a fouth page table level in the dart
driver and its io-pgtable [1].
