dt-bindings: iommu: dart: Add t8103-usb4-dart compatible
...
This DART variant is found in the t8103 (M1) SoCs and used for the
USB4/Thunderbolt PCIe ports. Unlike the regular t8103 DART these support
up to 64 SIDs and require a slightly different MMIO layout.

t600x SoCs use this DART style for the Thunderbolt ports, and t8112 SoCs
use them everywhere. Add a compatible for it. No other binding changes
necessary.

The M1 Max/Pro SoCs come with a new DART variant that is incompatible with
the previous one. Add a new compatible for those.

dt-bindings: iommu: apple,dart: Add power-domains property
...
This will bind to the PMGR pwrstate nodes that control power/clock
gating to SoC blocks. The DART driver doesn't do runtime-pm yet, so
initially this will just keep the domain on permanently.
