arm64: dts: apple: t8112: Add nodes for integrated USB Type-C ports

Add device nodes and connections to support USB 3.x on the SoC's
integrated USBi Type-C ports of M2-based devices.
Each Type-C port has an Apple Type-C PHY for USB 2.0, USB 3.x,
USB4/Thunderbolt, and DisplayPort, a Synopsys Designware USB 3.x
controller, two DART iommu instances and a CD321x USB PD controller.
The port labels use Apple's established naming scheme for the ports.
