Add basic support for the Kontron KSwitch D10 MMT. It comes in two
variants: "6G-2GS" which features 6 Gigabit copper ports and two SFP
cages and "8G" which features 6 Gigbabit copper ports (where two are
2.5G capable).
For now the following is supported and working:
- Kernel console
- SFP cages I2C bus and mux
- SPI
- SGPIO
- Watchdog
