arm64: ZynqMP DT changes for 6.9

dt-bindings:
- Describe firmware for Versal NET
- Describe all firmware child nodes
- Align versal-fpga node name with dt schema
- Describe k26 rev2 and kv260

DTs:
- Align firmware node with dt schema
- Add an optee node
- Describe reset for CANs
- Update ECAM size to discover up to 256 buses
- Describe assigned-clocks for uarts
- Add u-boot node
- Comment SMMU entries
- Align dwc3 nodes with dt schema
- Rename i2c groups to match dt schema
- Small DT updates (comments)
- Fix default clock frequency for si570 (zcu102, zcu106)
- Add output-enable pins and cover MIO38 (SOM)
