dt-bindings: iommu: apple: Add Apple M3 compatibles to DART and SART

Apple Silicon Macs use two types of IOMMU, SART (for NVMe) and DART
(for everything else). On M3 (t8122), the SART is compatible with
the t6000 (M1 Pro/Max) one and the DART is compatible with the
t8110 (A15) one. Thus, add a t8122 enum variant to the compatibles,
but leave the base compatibles unchanged.
