arm64: dts: apple: t60xx: Add nodes for integrated USB Type-C ports

Browse source 
Add device nodes and connections to support USB 3.x on the SoC's
integrated Type-C ports of M1 and M2 Pro, Max and Ultra 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.
M1 and M2 Max based Mac Studio device have two additional USB Type-C
ports on the front which are driven by an AsMedia PCIe USB controller
and integrated USB hub. These ports are not covered by this change.
The port labels use Apple's established naming scheme for the ports.
